One of the best 45 demos I've watched. I've wanted one my whole playing life. Best Marshall I've ever tried. One day.....
Yeah they are great! The best one I ever played was one of the new handwired reissues. So touch sensitive. If I get one again that's what I will buy! Used of course. haha
@@drwhiteguru I had an original that I gave to my son in LA about 4 years ago. Completely unmolested, and in 10/10 condition. I mostly prefer the Boogie 2C+ for my playing, but hearing your demo has me leaning towards buying this one. Sounds super close, to my ears.
cool demo. Congratulations
Sounds awesome man
Years ago I played a JTM45 RI through a Marshall 1960TV and it was heavenly!!!
Yeah, that is a great cab for that amp…
Just bought one!! What a spectacular amp!! I have it running into both a Mesa recto closed back with V30's and a Mesa Lonestar open back with C90s.. Absolutely amazing tone!!
Oh boy! Congratulations!
What kind of Music do you play?
Those are good speakers but you definitely should try an Alnico like the originals had. I tried a bunch of different speakers with it and I like the Alnico the best.
Scumback S75-PVC Alnico are a boutique recreation of the speakers that came in the original Bluesbreaker JTM45 combos from the ‘60’s.
The holy grail tone is the Beano album with Eric Clapton (John Mayall Bluesbreakers).
www.scumbackspeakers.com/scumnico.html
Also try some old 12AX7 preamp tubes from the 60s it makes a huge difference in your tone. I tried about 10 different types in mine.
Good luck with your amp!
@@drwhiteguru I've been hitting everything from bluesy rock to some harder rock... working on composing some unique things as we speak. You hit it on the head with the Beano album!! WOW that's what this amp is all about. It can get expensive searching for that "perfect" sound. I have some Alnico's on the wish list. Sounding pretty good with my 2012 Deluxe Goldtop so far. I bet some Vintage tubes would be amazing. Thanks for the videos!
Brian sounds like a perfect combo! I love Les Pauls, I just got a good one a 2016 Limited Edish Walnut top. Good luck on your songwriting that's where it's at! Send me a link sometime I'd love to hear something.
Keep Rocking!

Nice sound, I want one
One of the best demo!!!
Thank you!
Great job
Sounds really good man.....I'm considering getting a JTM45 RI
another amp shredster von kelster...lol
thanks!
I actually liked the clean tone
The clean boost from the OCD sounded pretty good [nods] *:)*
Try setting the B3, M6-7, T6, P4-5, TCV4 and then add in a little of the OCD. I've done this and it's out of this world tone
Great video, Tim…thanks *:)*
Thanks! I don't know what B3, M6-7, T6, P4-5, TCV4 means...
@@drwhiteguru umm…sorry Tim.
Bass 3. Middle 6-7, Treble 6, Presence 4-5, Treble Channel Volume 4ish …and maybe Normal Channel Volume to taste or not at all
Oh.. I get it. I'm a little slow on the uptake...
@@drwhiteguru Lol, right on! JTM45s are a little darker than say, a Super Lead. The 45 tends to sound a little cooler if you keep the Bass pulled back and push the Mids a little more than the other tones. To keep the attack tight, I usually don't push the Volume much more than 4 or so…that seems to be the sweet spot and going higher can get mooshy. If you're into gadgets, Schaffer has a boost that's really cool and some people are talking about. It puts the final touches on that [Angus Young] vibe…or any vibe really :) Cheers!
YES they are darker. The OCD tightens up the low end. Haven't tried the Schaffer.@@creamygoodness3018
I did the whole rebuild with the AC30 through Dave Petersen as I was saying before. I replaced the output transformer with a wooden mercury magnetics output transformer. the choke is a special choke from Mr. Petersen that he sent me. It is able to handle the extra power by rewiring it. I think it is listed with Greg Fryer from Australia. He's the guy that rebuilt all of Brian May's amps. In pics of his amp line up , you can see his logo on all of his amps. The choke is able to handle 300 milliamps or something like that. The choke that mercury magnetics sells is not the same choke. Mr. Petersen left England for the far East to live. I still email him from time to time. He's a great guy. he worked for Marshall and Vox. He originally built the Brian May special edition amp. Mr. Grin rod from England was the engineer that put out the amp. He was supposed to give an exact duplicate of Mr. Petersen amp schematic, but he completely deviated from the original schematic, which ruined the amp in my opinion. Mr. Mike Ryde website gives full colour pics of the rebuild and explains it in detail. A guy from Ohio named Greg Covington helped me a great deal. He originally dealt with Mike Ryde on his own rebuild. he also has demoes of this amp on you tube. The caps were replaced in my amp with Sozo caps and carbon comp Allen Bradley resistors. Also the Celestion blue alnico speakers were replaced with the UK made speakers. Everything included wound up costing me about $600.00 for the speakers, choke $75.00 $300.00 for the Mercury magnetics output transformer. The rebuild was very simple, but you have to follow Mike Ryde instructions on his website. The sound is exactly like an old 60's sound. It's bloody bang on mate. I could not be happier with this amp now. The valve treble boost in the second channel is great. We'll worth doing. Originally I bought this amp for $1200.00 from a guy here in Canada. I traded an old Clapton strat for it. he was happy with the trade. He said he hated that the amp was so loud and the ghost noting that occurs in this stock Brian May amp. Once it's rebuilt, it's an entirely a different amp and for the better. Beatles Revolver album where Harrison plays one on Taxman. Cheers mate
Great vid sounds fantastic 👏 you should get some nos 6l6 tubes I have the sylvania 12ax7 tubes also same with The Rca tubes thats most likely why your amp sounds so good well the les paul helps . ok your playing also !
Thanks Paul, yeah I did get some NOS 6L6 power tubes still in the boxes but I sold the amp! Now what am I going to do!? I got some EL34's too (Siemans) Playing a Matchless Excalibur these days.
Are the two Alnico Blues in an open or closed back cab? Nice playing by the way.
Thank you! They are in a semi open back cabinet.
It's a Vox AC30 Brian May but I'm only using the speakers. They are plugged into the Marshall.
The JTM45's from the 60's used Alnico speakers too and they sound good. They have a certain sizzle in the high end that I like.
In fact every amp I have sounds good with them, from a 1970 Fender Princeton to my Matchless Independence.
Mogami cable? spare no expense. And it does make a difference thanks for the post.
hey tim my jtm sarted o sound so dark, midrangy and no dynamics while driven or using overdrive pedals
i changed the preamp tubes, the clean tone became better but still in overdrive mode there s a loss of treble,
is this a power tubes problem?
Maybe it needs to be re-capped? What year is it?
Hi how can I enjoy the Marshall JTM45
At home I am at a crossroads whether to sell it and buy a small amplifier or is there a possibility to save our friendship and keep it thanks
You should throw a pair of KT-66's in there.
They'll break if you throw them.
Good demo, Is that a Standard Gibson LP?
Thanks. No it's Les Paul Studio. Supposedly a Standard without the binding.
I have a same amp, but can't level up above 2 because it's too loud. Do you use an attenuator? How can you level all the way up?
Just do it! Turn it up to 10!
It stops getting louder at about 5 or halfway up. After that it gets more gain.
This is a Marshall, they sound best all the way up. Use your guitar volume to control the amp.
That is the way the classic sounds of the 1960's and 70's were recorded.
No, I was not using an attenuator.
If it hurts wear ear plugs.
Try it you'll like it!
Thanks a lot!
Seong Je Goh ... I have the same amp. When i am worried about disturbing my neighbours across the street, I use an attenuator. It's a Fryette PS2. it's expensive, but it does a very good job at maintaining the tone of the amp cranked, even at low volumen.
Hi , I have the exact amp the Brian May amp. I rebuilt mine to Dave Petersen schematic in conjunction with Mike Ryde rebuild that he published on the net. Much better sounding after the rebuild. my question to you is how do you keep from blowing the speakers on the Vox being only 15 watts each. I have a Ceriatone bluesbreaker JTM 45amp and Nik from Ceriatone said not to use these Celestion blue alnico speakers with it because they will blow up full. I've tried the amp up about eight with no problems but am leary of playing it up full. I mean May played through these blues up full for years and didn't blow speakers, I don't think. what's your take on using these speakers up full. thanks from Michael Newell from Niagara Falls
The Marshall is 30-35 watts and isn't that loud, but the Vox is a VERY loud 30 watts so I just took the risk. No problems. I didn't keep the JTM45 long.
I had to work too hard to coax anything out of it, and it didn't make me smile when I played it, unlike the Vox BM!
Congrats on the Petersen upgrade to your Vox BM. I would like to do that someday too. BTW how much did it cost you? If you don't mind me asking...
@@drwhiteguru , I never did get back to you on the cost of the upgrade on the Brian May Vox. The output transformer was really the only real investment. The Mercury Magnetic output transformer was a Woden clone. Cost me about $300.00 USD. The only other part is the proper choke that is made and sold by Petersen. He lives in the Philippines now, but the guy who is in charge of selling the choke and schematics lives in Italy. His email is alfa758@libero.it. His name is Valerio Capodagli, but goes by the name of Valerio May on RUclips. He has a red special guitar. He does Queen covers on RUclips. If you are interested in still doing this mod, it is not that expensive. The choke from this guy Valerio would run you about $50.00 USD plus shipping. This mod from Mike Ryde's site shows you colour pictures step by step. It's really something you could do yourself. But you could always get a tech to do it. The mod is relatively simple and makes a huge difference in sound for the better. Actually my Brian May Special Edition amp is in L.A. right now getting fixed at Kruse amplification. The capacitors and the carbon comp resistors are not that expensive. I used Sozo caps from Antique Electronics in Phoenix, Arizona. Carbon comps you can get on EBay. Just one other note. People said years ago that the Chinese made Celestion blue Alnico speakers were inferior to the UK made Blues. I have both and they are identical. Those guys are full of shite. Anyways if you still have the amp and want to mod it, do it. It's worth it. If you need any advice on the rebuild I could give you advice as you go along. Also one thing they do in the mod is to get rid of that horrible treble boost circuit. That's easy enough to take out. Cheers Michael Newell from Niagara Falls, Ontario, Canada
Is the les paul studio stock? Could we get some more details on it? Looks gorgeous
Thank you! It’s a Les Paul Studio 2011 stock, nothing special. I like it but one day I’ll get a Traditional or one from the “good wood era” early nineties
Tim White I had a 93 in wine red and it was dead as a doornail, I guess there's good ones and bad ones from every year! You sound like you found a good one already
Thanks, it's pretty beat up now, I like it that way.
and the bassman was a copy from a tube manual from a tube maker,
Great sound and playing !....you still have the amp ?
Thank you! No I don't It was O.K. but nowhere near TopHat Emplexador or Matchless Independence. I played a handwired JTM45 reissue and it was AMAZING!
@@drwhiteguru Thanks for your reply !!.......Cheers!
would love to have heard both volumes at 3 o'clock with the ocd as a clean boost
I did that for a little bit @ 6:10
In your opinion, would you say that is the next best thing to a 1967 50 watt Blackface Fender Bassman with a "Marshall" mod in the bass channel?
I have no idea, I haven't played a modded Fender. The 1966 Blackface Bassman I had for a while sounded good for clean but the distortion was horrible.
The low end was an undefined mess and the whole gain quality undesirable.
The Tweed Bassman sounds great though, and as you probably know was the inspiration for the Marshall JTM45.
Thanks Tim
All power tubes 6l6? Did you consider to mix EL34 with 6L6? Just asking
Yes 6L6, no I didn't because I'm not adept at re-biasing. But I did use ANOS preamp tubes which really made a big difference in this amp!
Can you test it with a Fender Stratocaster? OK what does it do, to jump wire from one channel to the other? I know it combines the channels, but what is the reasons, apparent benefit of doing that?
Michael, I sold the amp, I may have recored with my Tom Anderson Strat on this shoot, Let me check. The reasons for mixing the channels is: they are voiced differently, so your blending two flavors with their own gain stages for a little more complexity in tone.
You are the first person to answer this, and give a real answer. Thanks.
I'm glad I was able to help! I checked my files and I did film about 15 minutes with my TA Strat on the same day. If you're interested private message me and I'm sure I can send you some of it.
Can you turn it all the way up with no attenuator and be in the same room?That's Angus Young territory right there.Great playing too.
Yes absolutely! However I think if the capacitors were replaced it may be quite a bit louder.
My vox ac30 is at least twice the volume all the way up.
When the power tubes add their distortion it sounds different than preamp gain, warmer fuzzier and way more compressed in the feel. It's nice not having a master volume the amp is much more dynamic and touch sensitive the way it should be.
I'm saving money for this! (im 15 and im even putting my school lunch money to get it asap lol)
Wow that’s great! Look just so you know before you buy let me give you some info...
This is a Marshall JTM45 Mkii reissue from the 1990’s. Not the most accurate reissue either. It has a PCB “ printed circuit board“ it isn’t hand wired, and they changed the circuit A little bit from the original.
Marshall made a hand wired re issue about five years ago which was so much better! I mean WAY better.
The key is HANDWIRED... they also used a more accurate circuit I’ve played one before nice and loud and the difference between the two was night and day.
You can find them used sometimes for about $1500. However if you want really good tone and want to know what’s going on you should probably join a forum like: the gear page. See link for A discussion on the good Marshall handwired reissue
www.thegearpage.net/board/index.php?threads/new-marshall-jtm45-hand-wired-30w.1385175/
One more thing… There are companies, small builders that make exact super high-quality reproductions of this amplifier even better than the hand wired Marshall if you can believe that.
Please check them out before you buy. Start with Germino.
www.germinoamplification.com/classic-45
Educate yourself and learn. I applaud you for your dedication saving your lunch money, that’s great! I hate to see you buy an inferior product when you can get something almost like an original for basically the same price. Used Germino Classic 45 sell for about $1500 used and will last a lifetime.
There are also companies that make kits which are high-quality and you can buy a kit amp put together for about $1000. Check out Valvestorm.
There are a whole lot of people out there who know the difference between a good amp and a great amp sometimes they are referred to as “corksniffers “you know, snobs... some are and some like high quality boutique gear.
What kind of music do you want to play? Do you write? I hope so...
Thanks for reaching out and I hope that you take a little bit of time to check out the info above,
All the best!
Dr. White
@@drwhiteguru WOW Just wow, thanks for all of that u wrote above, ill surely be more careful and read a lot more about that amp topic. About playing.. i mostly love playing things like CCR, ZZ Top, KISS, Bonamassa, SRV, Beatles, Tom Petty, Satriani, Eric Clapton, John Frusciante, even rockabilly like Chuck Berry and Elvis... those amps just shout the blues sound i looove. I also love Slash, idk if i could get a tone like his with this amp(maybe with an ocd i could). About writing, I'm still going to a teacher and he always gives me homework to write a solo on a riff we learned, or just to write some riffs.
@@drwhiteguru So I found a guy who makes amp clones here in Hungary, he can even add an fx loop or a master volume knob (he may take extra money for those mods) for 1500euro. (also, the pricings are a lot higher in just everything here than in the usa)
c0nfused Sounds like your listening to the right people! You have some good influences.
So I want you to check out this company: Ceriatone they make handwired clones in Malaysia. They are very inexpensive, ship internationally and The owner Nick will respond to your emails!
It sounds like you want the old Marshall sound and they make lots of different ones including a clone of the Appetite for Destruction Marshall that Slash used.
I know lots of people who own these amps. The reason they are cheaper is because labor is cheaper in Malaysia.
Check out this link: www.ceriatone.com/products/
Look under the “British Style” section.
They even have small lunchbox size versions that are lower wattage but loud enough for a band. They look a little funny because they are small but they sound fantastic they cost about US $650. I think Euros are about the same as US dollars.
They also make hot rodded Marshalls that do the low gain vintage sound and high gain super high gain in one amp. Check out the Yeti or son of Yeti.
I’m glad your taking lessons it saves a lot of time. Make sure to learn how to write songs too. If you want to make any money...
Good Luck and keep working hard!
@@drwhiteguru Holy that small Silver Jubilee looks awesome! To be honest, I was about to start saving for a Silver Jubilee cause Slash got me into this type of music. Maybe i'll get a luncbox edition of it later:) Their JTM45 clone sounds just amazing!
Sir I'm.a begginer ,,looking for classic rock sound ,, love vox ac30 and your playing of this jtm 45 blows my mind off ,, please suggest me which one is better for me and can I use this jtm at my home? Thank you
Wow! Two good choices. So I like the Vox AC30 better than the JTM45. I had both and sold the Marshall, kept the Vox.
It has more gain, feeds back easier, is more touch sensitive, the cleans are chimey and the dirt is angry.
Bypass the master volume for best results and turn it up!
What kind of music do you play?
Tim White I like classic rock ,like led Zeppelin ,queen ,and specially just fascinated by the royal Albert hall Jimmy pages sound ,,I want my tone to be like that,,high sustain with clean mixed with little overdrive ,,I also like Garry Moore tone
Sir I have one more problem,,that is ,can I use the ac30 in my house ,, isn't it too loud?I have to choose such an amp which I can play at my home and small gigs as well as express that dream tone what I have mentioned previously
Ha ha! Everyone has the same problem: they need big amp tone at low volume.
A few ways to do that I'm sure you may know:
Use a clean amp and get boutique pedals for your dirty tone.
Use an amp with a Master Volume.
Use a small tube amp you can turn up without it getting too loud.
Use an attenuator, like the Power Station, Rockcrusher, or OX.
Use Modeling: Fractal Audio Axe effects 2 or 3, Kemper, Line 6 Helix or POD HD.
My favorites are: Attenuator, semi driven amp with an overdrive pedal, and Modeling in that order.
Good choice on the Royal Albert Hall tone. I'm sure you know that was a modified Hiwatt amp. A couple of companies make a copy of that Hi-Tone and Reeves I think.
It sounds like you are drawn to classic British amps with medium gain levels as I am. I've owned a lot of them and I think some of the best are: Vox, Marshall, Hiwatt, Matchless but the best amps for the money used are TopHats or old Budda Twinmaster or Superdrives.
Tim White thank you very much for your valuable suggestion,,sir ,i am aware of the hiwatt heads which were specially customed built for jimmy page ,,can I be able to play vox ac30 or a good Marshall at home following your advice above,,,I'm very much excited as a beginner towards that classic rock sound ,,I will definitely check out the budget affordable amps you have mentioned,,thank you again
what has to be done to run 6l6's versus the el34's?
I'm guessing a re-bias for EL34's. You may want to
Try KT66 too That is the classic sound for this amp.
The best new production KT66 are the Gold Lion reissue.
NOS ones are super expensive for a matched pair.
JC, you'll have to change two resistors and readjust the bias in order to run 6l6s.
Your amp should sound like this John. If it sounds bad when cranked up and, seeing how the FX loop stopped working on it, there may be an issue with your amp. Either the builder botched it or, used sub standard parts / components.
IF you need NOS tubes, let me know and I can source anything down to authentic Mullard, Amperex, TungSol, Telefunken, Siemens, Bendix, and RCAs.
This amp sounds nice and warm just like I told ya it would. IT also sounds smooth just like the Billy Gibbons old small box Marshalls he used to use.
This demo sounds fantastic. I have heard a ton of plexi heads that sound thin, buzzy, harsh etc. This amp, for the money, sounds fantastic.
IMHO the JTM45 should be run with KT66 power tubes period.
Yes they should like the originals. In the 90's Marshall Re-issued the amp with 5881's but the bigger sin was making changes to the circuit which they did. The latest re-issue part of the Marshall Handwired Series 2245THW is much closer to the original, with KT66 and tremelo.
You got me there buddy. Great demo and great sound.
I read the very original JTM45 used 5881's. They soon switched to KT66's, which is the one most people are familiar with.
marshall should have put a master vol in the back of these and the plexiglass ri ,,,....they are useless with out em unless your on a stage
On the back?! No way! First of all, There is no MASTER volume, just volume. This amp doesn't need a Master volume that's part of the sound and FEEL. Master volumes choke the dynamic feel out of an amp and you need to get the power tubes breaking up that's part of the sound. I hate leaning over the top of an amp and adjusting something and besides, Its a re-issue. ;P
@@drwhiteguru I and everyone I know has master volumes installed on vintage plexis they are just way more usable that way . They are mostly always in the back so you don’t see them fucking up the front panel. It’s pretty common
@@maxtwentynine5968 Yes it is for Modded Plexis, they put knobs on the back. Some of those sound great too! They never put enough gain in them for hard rock without using a pedal or getting it modded. Now they do but the old Non MV ones sound the best all the way up on 10!
@@drwhiteguru I’m talking about post phase inverter master volumes we get done on older non master volume Marshall’s . They should have them done to reissues so we can play em without blowing our ears out . They sound better than using a power soak to my ears
@@maxtwentynine5968 Never tried one but I do like the Rivera Rock Crusher it's pretty transparent, for recording I have the cab in another room, I also just got a Fractal Axe Effects Modeler after hearing Metallica switched to them live and for medium to high gain stuff they are very very close especially with 3rd party IR's. Works great on my analog synths too.
The Handwired JTM45's sound so much better than this one did and I hear was a much more accurate circuit to the original,
So this is the one Gary Moore used on still got the blues? Pretty sure he got the first reissue they ever made in 1990 and pumped it into sonic heaven with a guvnor pedal
I didn't know that! Maybe... I'm sure he could make an amp like this sing with a Les Paul and a Guv'nor! I actually have one of those old Guv'nor pedals from the early 90's it still works too.
It's not a marshall unless it's on 10
What?!
That was a compliment excellent video all I meant is Marshall sound best cranked all the way up LOL. I think we're in agreement.
Alnico blues sound shyte with gain imho. Never liked them (I own an AC30 with them).
Prefer ceramic with the JTM45.
What gain? LOL Yeah Greenbacks are great, but the OG had Alnico, semi-open back. Ever try Scumback? Boutique re-creations of the pre-Rola pulsonic cone Celestions? They sound great!
Talk normal,
The sound is Alnico blue’s one. Much influence from the speaker. Bad video
It was great, just like what the blues breaker amp had in
