- Metallica riffs with the Mark V that has AT7 tube in V4 compared to the JP2c.
Mark V: has the Jan Philips AT7 tube in V4
JP2C Power amp: 60w
V Power amp (45w, variac, tube)
JP2C: Gain pushed
JP2C: Presence Pulled
JP2C: Shred not engaged
GEQ: Both On (Varied depending on song)
Cab: Mesa 2x12 Vertical Rectifier
Mic: Shure SM57
No post processing
Both sound great imo
Sounds effin great!! The Mark V sounds good, but the JP2C has just a little more punch to it. The set up is really handy for experimenting with clean, crunch and solo sounds. The shred setting is also really cool with the JP2C. I love it!!
The Jp-2c is darker sounding, more grind & whine in the V, the JP-2c is more raspier & more punchy. Both kick ass.
We all know the JP2c is great. We all know IIC+s are awesome but this V is amazing too. Again, they modeled it from a non-eq IIC+.
JCKCPA couldn’t agree more. I love the V
Overall, I think those are comparable tones. Great examples.
Great comparison! To me the JP2C has a little more punch and clarity. Im currently debating between both of these heads...
To my ears, I think the V's tone is a bit more defined for a couple of reasons. The V has a smaller cap allowing less bass come through the the preamp circuit and less sag in the power amp but the JP sounds and feels far more powerful. Between the two, It's a really tough call. If you're after metal with core sounds being clean and distorted I'd go the JP. Midi is super handy as well. If you want versatility and into a bit more bluesy type and rock playing go the V. My intention was to sell the V once the JP came in but they are different enough to keep both.
Sweet... on my V I hadn't pushed the treb/mid up that hi at low vols, but with a Captor and a 1x12EVM off of the -20db attn it works really well. I'm digging it thanks!!
Subbed great comparison! To my ears the JP-2c sounds close to classic thrash Metallica sounds but the V sounds good as well. I'd go with JP-2c
Hey! From different demos I've seen, I think that the JP2C is not as tight and it has this "crunchy" sound to it, do you think this is correct? Everyone says that JP2C is better but I think it's missing this super tight thing that I like so much about the V (I mean, JP is still tight but not as much as the V). And I don't like this crunchy sound neither, you can really listen what I'm talking about in ola's demo for example... do you think these differences I'm ponting out are correct?
It's pretty hard to judge them from different videos and there are not a lot of VS videos.
By the way, these differences are also pretty obvious in the official mesa video where petrucci compares mark V with a real IIC+ (I prefere the V by far in that recording), should I base on these ideas to choose the V over the JPIIC?
Hi Cesar. The original c+ has pull controls that lets you alter the tone. On the V and on the iic+ mode I think the Pull Deep control is hardwired to off (I think). So it will naturally sound “tighter” because there is less bass passing through the circuit. This is part of why you hear a difference betteeen the iic+ and the V in Petrucci’s demo video since Petrucci uses pull deep. Petrucci’s iic+ also has more gain so you could easily get a iic+ tighter than you heard by pushing the pull deep control and maybe dropping the gain a little bit. The V was also modelled off a non GEQ C+ which has its own inherent differences. To your original question, the JP2C is modelled off Petrucci’s 60/100w HRG head with graphic EQ that differs in circuit to the mark V. And the pull deep is hardwired to on. With this the tone sounds bigger but also can be heard as less tight or a little more rounded. So I kinda agree with you. All of these amps that have the GEQ can generally be sculpted to sound more or less like each other, at least in recording. If you play metal, prog or heavy music I would totally get the JP over the V assuming you want a clean, heavy and lead tone all with the same type of sound being c+. If you want different flavours in the amp channels then the V is more versatile in that regard but doesn’t have features like dual GEQ, midi, cab clone etc. if I still had the V I’d add another video to show you what I mean but I no longer have it. Also the mark IV mode has the bigger deep sound so if you went the V and wanted a bigger sound you could just change to mark iv mode which is more fluid and has more bass. Hope that all makes sense.
@@Lordiesel awesome man! thanks a lot for that answer :D it's really useful, just one more question:
What about the sound in the room? where you able to get that huge sound that I've read about the JP2C (or mark IV) with the V if you tweak it? because in recordings, I kinda prefere the V tone (less crunchy and extremely tight vibe) but people say that the sound in the room is way better in the others.
Load up that mark V with some 6L6 tubes and that’s perfect Metallica tones right there.
Отличное исполнение! Good attack
Fucking nailed The Shortest Straw with the V
Thanks glad you enjoyed. Yeah chunky as hell right?
Wow you run your mark v pre gain mids and treble way higher than I do, sounds good!
I'm off to try it out on mine! 👍
Kay I have my setup at pretty low volume and the settings work well for that and might not translate at high volume, Whenever I’ve tried playing loud I need to back them down a tad.
Killer tone
Both sound great!
Both great amps. All Mesa amps are great amps \m/
!!! just my taste : the V but whatever you sound so good !!!
As a owner of a mark v 90 watt the jp2c just has this frequency that the mark v just doesn't have.. I'm currently waiting on my jp2c waiting time is estimated until June. ☠
The JP is the perfect metal performance amp. The V is incredible too, for me it was just a little bit of a shame that the volume 1 was preset to 7ish. The JP suits high gain a bit more with the higher preset levels and pull gain controls.
My Mark V's channel 3 is always stuck on Mark IV mode, while channel 2 on Crunch.
These are definitely my two favourite modes as well. Crunch with gain and treble maxed out is thick as hell and running ch 3 in triode 10w adds the that harmonic halo they mention in the manual.
@@Lordiesel The crunch can be boosted with an OD to go into very high gain territories. Honestly, the Mark IV doesn't need any boost. A slight more bass in the preamp section gets the sound a little muddier and nastier, while staying focused and precise. You REALLY need to over do it to get a bad tone. Those who can't dial a Mark are honestly not even trying. XD
I wish Mesa would have developed a JP (1Ch) Loan Star (2Ch) Mark IIC+ (3Ch) Mark IV amp. I know that's basically what the Mark V is. But a Signature amp with this configuration would have truly represented JP's overall sound. Two identical channels on his MK2 C+ is redundant (even if you can tweak them individually with the duel equalizers). How about a James Hetfield Mark IIC++ now.....
On the V I actually prefer the IV mode for rhythm and c+ mode for lead.
I quite like that on the JP2C having the duplicate channel with push pull combinations. Essentially gives back some of the tonal flexibility that internally fixing these settings takes away. By having ch 3 set higher in with gain pushed we essentially get 4 switchable volume 1 settings with 6.5 - 7.5 on Ch 2 and 8-9ish on Ch 3.
Remember that METALLICA uses way less gain. about on half with the gain knob pulled.
Jonathan Clough thanks Jonathan. Yeh I’ve tried out the settings from their original recording sessions. Key differences, at least of the JP, would be that I’m using Ch2 with the gain pushed resulting in an internal volume of approx 6 rather that the 9/9.5 they were using. I run the treble a tad lower reducing the overall gain, push the GEQ a lot less and also have the channel masters set low. Setting the gain at 5/5.5 gets there on Ch3 with gain pulled and the treble run to the equivalent of about 7.
For the V, it naturally has far less gain so needs to be round the 2-3 o’clock range to have enough gain. Running the original settings with low gain and high treble gets a more vintage roaring type distortion since there’s less saturation. I tend to avoid these settings because the shred function is a bit noisey and squeals when you set the treble that high. So I compensate with more gain and less treble. Thanks for watching!
JP-2C for sure
Nice play though. Both are great amps but when dialing in the old Metallica sounds on a Mark V, I prefer using the Mark IV settings - it seems to have that bit more "beefy sound" and snarl that the IIC+'s had, in my ears at least. The best of the two is the one you like the best.
That JP-2C is tasty though. I gotta say that midi control and two graphic EQ's does tip the judgement in favor of the newer amp.
I've regressed in recent years to the lower wattage Mark V amps just because, even in practice with a band, getting the Master to 2 oclock on a big Mark V is just too loud. If I run it less than that, the lead tones sound like Kirk Hammet with flat batteries in his EMG pickups. :P
I alternated between c+ mode and IV for that tone. Both sound great. The IV mode has more sizzle, brightness and generally bigger sound. And you're right, probably a bit more comparable to the JP. I run my masters at 1-1.5 on the older marks and below 10 o’clock on the newer ones. ..... and then it goes into a load box where I reduce at least 50% assuming a linear taper on the attenuator. They are very loud. The Mark IV has the most ridiculous taper on the output control. Too quiet to deafening with the slightest movement.
I personally like the V better. idk exactly why but i do
Top Snek in a lot of ways I do too. It has more definition in this clip which is helped by the tube swap. The tones in both can be shaped so differently though with the tone controls and GEQ’s so it would be achievable to get both to sound like each other
I can't hear a big difference but it's not easy on RUclips.
The Shortest Straw its meaty and beefy xd
How does the Mark V:25 Mini in IIC+ mode compare with the JP2c in IIC+ mode?
hi. I haven't had too much time with a v25 so I'll base my opinion on trying it out at the store and research online. Firstly, the Jp2c doesn't really have a c+ mode, it is a c+ based on Petrucci's favourite model being a 60/100w with the 105 transformer. The c+ mode on all the V models are based off a different variation of the c+ which was a simul-class without the graphic eq and a different transformer. The difference in tone between JP and V- C+ mode is that the JP2c sounds thicker, bigger, more liquid and has more 'bounce' . The V C+ mode is tighter and more immediate but also thinner., as you could probably hear in this video. You can still get it to sound thicker but you need to change the settings to compensate. The difference between the V25 and V90 is that the v25 has a slightly higher gain internally fixed gain setting so you don't need to drive the gain knob as high to get the some amount of saturation. Also the v25 also has different tubes in the power amp (EL84 I think) as opposed to 6L6s in the V90w. I haven't had too much experience with EL84s but from what I understand these tubes are more preferred for rock and blues whereas 6L6's are fairly standard for heavier tones. This would change the gain characteristic. Not for better or worse, just different. All exceptional amps with killer tone.
Thaymz I think at least part of the 6L6’s lead over EL84s in metal amps is power. Four EL84s will usually only get you about 30w or so, whereas four 6L6s tend to put out closer to 100w.
There are tonal variations as well, but I don’t think EL84s (or 6V6s) will have much of a chance taking off in really heavy music unless musicians in that genre start embracing lower-powered amps (or literally heavy amps with like 8-12 or so power tubes).
I want to know peoples blind folded opinion. The difference between the two might be as simple as mic placement. I didn’t read the description. At least on sanitarium it sounds the same if you boost the volume. If you watch the with with Johnny playing the original vs the mark v the mark v suddenly sounds sub par. On that demo there is a HUGE difference. The mark v I tried with a USA dean was berserk.
It could be also that Petrucci wasn't running any 12AT7 preamp tubes. Most likely had stock 12ax7s. Whereas this Mark V did have the 12AT7s. That closes the gap a little, for sure.
Any tips to make my Mark V more liquid under the fingers?
The quickest and easiest, if you aren't already, is to use Mark IV mode. It terms of sustain / and how liquid the amp feels the order is IV, then c+ and Extreme having the lowest level due to the negative feedback from the poweramp.
It might seem obvious, but the Gain and Treble knobs will have the most impact. The manual is great and has a lot of detail but is quite conservative on the suggested settings ie - it recommends Gain at roughly 2 o'clock and Treble at 1-1:30 for high gain. I disagree with this generally as the full range of the knob is useable and for liquid you need treble and gain closer to 3o'clock or higher. In the original mark series amps when the dials were numbered, typical high gain settings involved setting the Lead Drive and Treble anywhere between 8-10 and it's even recommended 7-8 as the baseline in the iic manual detailing that above 7 the Treble acts as increased gain rather than adding treble to the preamp. Not to mention, there was an additional drive knob (volume 1) which you could set well above what the V has been internally set to which is 7-7.25. If you watch the c+ vs V video that Petrucci made following the release of the mark V you'll see his Gain on the V is set to max. Even on his JP2c video it seems like he also sets channel 3 gain to max for his lead tone. So would recommend just increasing these and not staying within the bounds of the suggested settings....which you might already be doing.
Otherwise, the following should also help:
- Triode setting on channel 3
- 10w power
- Bright Switch on
- Higher output pickups
You could always add a boost in front but I personally don't think it needs it. If you max the G / T knobs its too much gain so there's enough gain available.
Thaymz Great thanks for the answer and for your time.
I want to know if maybe that missing point in my amp is the A7 mod on the preamp tubes cause my amp is loaded with stock tubes and thankfully to your videos i’ve noticed this mod and after some research i’m really curious about this mod.
The problem with my amp is the ice picky top end and the fuzzy soul when i turn up the gain on channel 3.
I was looking into the jp2c cause i find it so smooth in that frequencies area when i listen it on youtube and in this video i can find your mark V pleasing in that aspect too and i think that tube can make the whole difference.
So, do you think i can benefit from this mod too and is it safe to do it for the amp?
I’m not a tech guy but i think i can change a tube if’ll be careful.
Thank you again.
Luciano Di Gennaro oh definitely. I think ever mark V owner should add in the at7. To be honest for me I never really found my V to be ice picky but I also never really play that loud. Not sure if the ice pick comes in at high volumes but I don’t think it’s every V amp even though they should in theory all sound the same. That said another thing I do is I never set it to 90w pentode. I generally use 45w, tube rectification usually which softens the sound and adds a touch of bounce or sag. I also use variac power for the same reason. I found 90w pentode to be stiff sounding.
As for the AT7 tube it changes the distortion character to be more granular, rich and harmonic. Can’t say if it feels more liquid but I definitely think every V sounds better for it. It’s easy enough to do being just a tube swap and the tube itself is fairly low cost too. This was my first tube swap so no need to be tech to perform. Just remove the power amp tubes first to gain access to preamp tubes and then swap out the v4 tube. Supposedly an AT7 in V7, in addition to v4, sounds great too. And both positions are said to remove any ice pick frequencies from the tone.
Hey sounds great. I have a JP myself and love it. Was wondering why you went with 60 watt on the JP. Was it just a volume issue? Thanks.
Hey man. Yeah just for volume. I play at home so no need for 100w. I attenuate the 60w down to about 25% as well so I don’t have it loud at all. Both 60 and 100 sound great
@@Lordiesel Hey let me ask you something. Does your JP sound different day to day? One day mine sounds absolutely amazing and the next it might sound less saturated or less gainy for lack of a better word. It always sounds good but some days I have to fiddle with the knobs a little.
Hey mate. Nah not really, the controls are pretty much set as they are for me. Mind you, I run them higher than most. Every now and then if I have issue with signal strength it’s either low battery in the guit or cable that’s on its way out. Have you tried swapping cables or if not that tubes?
@@Lordiesel I have changed the battery before and it sounded maybe a bit better. I never thought about the cable but it kinda makes sense after some different situations I’ve encountered. I will try a new one. Sometimes I wonder if it’s not just me hearing it different from one day to the next really. Thanks man.
How’d you go mate? Could be just the ears playing tricks.
I preferred the 2C, at first, but after listening again the Mark V is not weird sounding at all, but a little too dark.
That said I have the mark v:25 and will be doing the AT7 mod also.
deasnutz4ever These are one possible combination of settings from infinite possible settings and cab, mic and mic placement is critically important in shaping the tone. If I ignore those elements and try to sum up the difference between these two I would say the JP naturally has more gain, power and bass. But with that said you can alter the settings to get them to sound almost identical. The JP still feels a bit more liquid though no matter how you set them.
Does that limited edition JP2C have anything different soundwise that the regular line of Jp2c's doesnt?
Hi Carlos. Tonally the amp is the same.
You have that torpedo reload there. If you would throw a well miced Mesa Oversized 4x12 IR recorded in a proper studio room on that it would sound better.
Hey mate. When I record I generally record DI, Signal coming from the load box and the cab mixed up with the SM57. As far as IRs now i mostly use the official Mesa cabs in the WOS plug-in.
Great comparison video! I'm trying to decide between the JP-2C and the MKV 35. It's so hard. I love classic rock as well as thrash/metal! I want an amp that can do it all without compromise and more than one channel. I can pickup either a used JP-2C or a used MkV 35 for the same price....
You can acheive a rock tone with the JP but the Mark V includes several modes that cater specifically to that type of sound, being tweed / edge / crunch and mark 1. If rock was a significant consideration I'd go the V, but a 90w version. You lose some of the key modes dropping to the 25 and 35w V's plus you forego quote a bit of versatility with the crunch mode being on channel 1 and no footswitch or midi options that can change the modes. The way I have my V setup is Ch1: Tweed, Ch 2: Crunch, Ch 3: Any - depending on what I'm going for at the time. The Mark v 25 and 35 are a bit more tailored to metal in that on ch 1 you have a variant of clean or crunch and then channel two is mostly metal with iic / IV / Extreme modes available. Way more options on the 90w due to the extra channel and configuration options.
I'm with you Thaymz. I love tweed and crunch. For 3 I'm usually on Extreme. Piddled with a JP2C day before yesterday. Do I need both? I'm a Les Paul guy. Also want a tweed Fender Deluxe and an ES-330, but I can't have it all.
hoplophobe sorry mate late on replying to this, didn’t see your comment. Do you need both? No probably not. But neither do I. If the V didn’t have crunch / tweed I’d probably just stick with the JP but they are unique enough to keep it. Same would go for extreme mode if you use that. Don’t think you’d be able to get that tone on the JP
I'd sell a kidney for either one
Jason Smith it’d be worth it
can i ask what pickups you have on this guitar ?
I think I used my RG with has EMG81 in the bridge for this but it was a while ago and can’t say for sure. If not that then could’ve been dimarzio evo but I doubt it.
45w / Triode / Variac for Metallica? You are killing some of the rawness with those choices dude.
These are just the settings I prefer. I use 45w to keep consistent with my channel 1 and 2 as I use tube rectification on those. To me triode has a more liquid feel, better harmonics and more sustain. I use variac to give the power section a bit more bounce as full power can sound a bit stiff. If I compare to the JP, the JP power section has far more sag so variac tends to sound closer in tone and feel. Happy to do another vid at some stage with 90w / Pentode / Full power to compare with those settings
The IIC+ was wired in triode originally...
4:28 sounds the closest to any of the tones imo. Sounds great! But still nowhere near as crunchy as a true 2C+. Maybe too much gain?
SKULL KRUSHER could very well be my settings. I think I had too much bass in the JP EQ and I didn’t base my settings on how Metallica recorded them. They used much higher volume 1 input (set around 9) and a gain of 5-5.5. On the JP that translates to using channel 3 with gain pulled and set around half way. Doing this sounds closer but these just aren’t the settings I use. For the album tones need to factor in, mics used, mic placement and that they used 2 Parametric EQs to shape the tone. I experimented with this recently and gets almost spot on to the albums
In the room, sounds far very aggressive.
i think that the mark v its a bit more clear and cuts a bit better in the mix than the jp2c
Yeah I tend to agree the V cuts through a little bit better in this video and probably generally I would say since it inherently had a little less bass in c+ mode. Either can be tweaked as needed with the GEQ to suit. Both great amps
When I use these settings I’m getting a lot of of seems like extra gain and a lot of low end on the jp2c
Daniel Henry hi Daniel. Could be a couple reasons for this. I run mine through the Torpedo Reload which attenuated the sound to a much lower volume. About 30%-50% of what the volume would be if it were not attenuated. That would have an impact on sound. These were also recorded with DI tracks that were re-amped into each amp and may not have been levelled the same as would be the case when guitar is straight into the amp. Mic placement is also a huge factor on final tone. Mine is also a 120v amp running on Australian 240v so there may be some impact on the poweramp. That said, run yours with lower Gain or Treble and drop the 80hz slider and you should be good. The Petrucci settings in the manual should get you the tone you’re after based on what you’ve described.
I liked the clarity of the Mark V better. Younger me would have preferred the JP though.
Christian Monteith based on this video alone I do too. Important to note that the amp settings used on the JP are just of the countless variations available for gain / tone / presence / GEQ. The clarity is definitely there in room and still learning how I like to set it.
That's the fun part about Boogies though, isn't it :P I'm still dialing in my Mark IV. Loving it so far.
Christian Monteith the best part 🤘🏻
A lot of head room on the jp huh?
Yeah - Huge amount of headroom. Most of my other amps are Simul class. That’s said I play at low-ish volume and attenuate even further. I think I’d notice the difference more if playing loud at gig volume
Sounds better than metallica man.
I used the same strings on Jp2c and it’s like I have to much gain in and it’s not super tight
Daniel Henry hey Daniel. Try reducing Bass to below 9 o’clock and also reducing the 80hz slider to mid way between mid line and top line. The pickups also make a difference too. As does tuning. You could always use shred mode to tighten it up but you shouldn’t really need to for 6 string guitars.
do you use mesa boogie 12AX7 in V1 ?
Generally yes. I don’t really tube roll in the preamp and v1 is a pain to get to in these so I keep them as is. I don’t think these were changed by the previous owners
What about you?
i've tested many tube in V1 actually but not mesa boogie 12ax7 for now, i may give it a try soon, i have a NOS telefunken 12ax7 in V1 actually (mark IV)
The Mark V sounds more organic imo.
YaBoi Donkey in this clip I think I agree. I put this video together when I first got the JP2C. Over the year I’ve learned how to dial it in a bit better and I prefer the JP over the V for heavy rhythm. I’ve kept the V mainly for the Tweed, Crunch and mk IV modes. I sometimes use the c+ mode for leads.
Soo no boost in front of the amp? Just guitar and amp? 😱
Nah, no boost. Just guitar into amp
So... ”gritty”. Black album sounds more polished to my ears. But the ”tension” and power is there.
Fredrik Svärd agree. I had too much gain, treble and Bass on the JP in this vid. I dial Gain and treble back to about 1:30-2 o’clock nowadays and it adds a lot more character. Bass between 8-8:30.
Thaymz Great playing. Bet guitars, micing and post production are huge factors too.
what configuration to use on the back of the Mark v
I use triode for channel 3.
Thaymz how much Reverb loop active or hard bypass
Rene Tello hi Rene. No reverb and loop active although I had no FX applied. I have the loop in order to use the output master.
Thaymz thanks
I think the Mark IV and Exreme are better modes than the IIC+ mode.
I think I liked Mark IV the best too. Extreme had its place but needed some pretty decent tweaking of the TMB controls. IV was definitely the most liquid to play and easy under the fingers. In triode mode as well 👌🏼
@@Lordiesel I agree. I go back and forth between Mark IV mode on my Mark V and my PRS Archon 100 for leads.
Is it just me, or is the JP slightly louder in these samples?
It could be. This recording was pretty early in my gear and recording days so I probably didn’t do the greatest job of levelling. It is close, but may not be exact. The JP has more input gain or Volume 1 so that could also add the the appearance of volume.
@@Lordieselif you turn up the FX Send level on the back of the Mark V, you can get even more saturation. This seems to be one of hidden features of the Mark V.
I can’t remember if I had it at noon or Full. I don’t have it anymore to try it out but expecting to pick one up on the future. I though I read in the manual that Slave level was purely volume and not impacting gain? was a while ago so can’t remember exactly.
@@Lordiesel Slave out includes the sound of the poweramp. Meanwhile, effects send includes only preamp gain stages.
When the loop is on (even when nothing is actually in the loop), the send level seems to add a gain stage. Not sure if this is a design flaw, but increasing effects send to 4:00 adds some great saturation. My channel 2 crunch is now a real metal alternative to channel 3. But this trick should be used sparingly to ensure channel 1 remains clean.
I see the love for the JP2C but have to be honest, the V kills....way more audible in a good way and a little more articulate. Can't honestly knock either amp for these songs though.(JP2C sounds a touch more like the original, I like V's tone though).
Timothy Martin both are great. The JP is more targeted for metal and achieves that easier while the V is a great all rounder. Both excellent
The JP sounds better than the V but neither sound as good as a real 2C+ or a III or a IV.
way too much mids. The marks are already mid heavy amps
In the mix I would agree, at least for the unforgiven recording. There's too much mid in the mix due to combination of 750 slider being too high and my mic and mic positioning. The tone controls are before the preamp and the mid control on the lead channel add thickness rather than mids. My settings have changed a bit since this video.
Imo mark soumds more metallica in my ears
They're both mark series amps.
V w/ AT7 wins for me.
...and I am now tearing apart my house trying to figure out what I did with my AT7s. I went back to AX7s about a year ago and this video reminded me of how much better it sounds with an AT7 or two in it.
Yeah man It’s gotta be AT7. I mean I loved the V stock but adding the AT7 really brought it to life.
@@Lordiesel tubes arrived this afternoon and the dragon is back. and angry.
@@dlpasco awesome dude. Were you a V4, V6 or V4 and V6 kinda guy? I used the jan Phillips in v4. What a quick cheap and easy way to make a great amp so much better.
@@Lordiesel I tried all three combinations, but using them in both v4 and v6 is what made me happiest.
mark v is better than the jp.any day..
Boogie sux. Their amp speakers suck more.
These sounds arent close to Metallica sound at all.
