Let's find out! Gear used: Marshall SV20 Studio Plexi Head Marshall Bluesbreaker Combo as a cabinet 2x Celestion G12M Greenbacks 1968 Gibson SG Special P90
Thanks! Do you enjoy the low power mode? I have used the 5w mode at the rehearsal room, to tame it down a bit... but it really lost a lot of low end and can sound a little bit boxy, I think
@tadask.4931 As Marshall will not release the schematics for these amps how would you know. There's a an electronics tech on here who has both amps apart and says apart from the top transformers positions and tube layout they are basically the same.
@@BlackDogOriginalThat could just be down to using different speakers. I have a Celestion Alnico gold and Harma tubes in my Origin 20c and its now a totally different animal.
I've owned this and a 71 super lead. The SV20 sounds very much like a plexi - BUT, the EQ behaves nothing like a plexi. It's way more active and can easily sound bad. My 71 sounded the same no matter where you dialed in the eq.
The Marshall SV20 does everything expected from a Plexi but has its own tone. It's neither a 1987, nor a 1959 clone, although similar, that's it. After all, output power and tone controls are different. The SV20 is notably quieter if its maximum volume level is compared to those of the other two amps, which makes it very usable. That also means that it overdrives at lower volume levels and the compression is different. The frequency response is heavily affected by the loudspeakers used. There's a tonal depth to the 1959 that isn't even present in the 1987 (probably due to enhanced bass response). However, I really like the overdrive coming from a 1987. To my ears (I might be wrong), the SV20 is more similar to the 1987 in that regard.
I would totally agree. I had a 1987x before and used it for many years of gigging. The 87 had a lot more depth - it pushed more air. It also had much more drive when cranked and created a rich and saggy feel. The SV won't get as saggy, it stays more tight. But you won't get as much drive when cranked to the max. Even with a big cabinet, the small poweramp section of the SV produces some higher mid frequencies which will shape some kind of boxyness to the tone. But in context of a mix or a band, that's absolutely okay. The 1987x can be a bit too bassy for this situation.
Sounds good to me! I have a hand wired Plexi clone and I think the voicing of those Marshall reissues is actually better from the demos I’ve heard. I only payed $700 for a non pcb version though. Doesn’t say Marshall but I can easily mod it.
@@Guitarjosii it’s dull compared to the reissue and too powerful without an attenuator. Those sv20 and siblings are a great amp for any band situation with the power and tones they do. I would love to see a good cab emulation output on them for the price but I have mics and so does any decent club or studio. Nice demo man. I’ll probably buy one someday even though I own 5 other Marshall style amps.
sounds great to me, would try it on 1 speaker as it then gets power almost like a 100w + 4 x 12. Seems best to start with treble at 0 and bring in highs with presence and Tilt knob first.
That Marshall is fantastic,but the sg special 1968 is absolutely out of this world,heavenly tone machine!!If anyone ask p90 are in Angus range tone,here good answers.
@@Guitarjosii Of course, Angus used his famous SG standard or custom 70/71 large pickguards fitted with t tops, but I find the p90 at the bridge of the special absolutely similar with that hoarse, open, aggressive tone, coupled with the Plexi. At the neck, like someone already wrote on another video of yours, the p90 has some Fender reminiscences, especially with the volume not at maximum, it has a cleanliness and an openness, which the hb on the neck forgets. I would like to hear you play with that SG also something by Clapton Cream, to see if even those creamy tones, and the woman tone, are within the reach of this splendid axe.I really think so, if there are the sounds of Angus, there will necessarily also be those of the late 60's Clapton. I also have 2 SGs, one of which is quite prestigious and rare (SG standard korina 1993 limited edition, mine number 202), they are good, but unfortunately far from the exceptional tone of yours. I dream of one like yours...the late 60s cost a lot now. I saw one in Bologna (I'm Italian) for 5000 euros, if I exchange the two I have (and adding a couple of thousand euros) I could reach the figure.
@@massimolombardi1367 I plan to do a comparison video between my 1968 Gibson SG Special with P90s and my 1969 Gibson SG Standard with T-Top HB Pickups. They sound really different to each other. Maybe that would help.
@@Guitarjosii i forgot you have also 69 SG standard!!!😅Wow,you have 2 fantastic vintage SGs.I can't wait to listen comparison,but could you give me already anything about which differences you hear in tone between special and standard?
@@massimolombardi1367 I can try but it‘s a bit hard for me in english. The P90 SG has a little more output, which is interesting, because you might think, that a HB might produce more juice, than a P90 single coil. But my T-Tops rate around 7.1kOhm, the P90s are around 7,5, if I remember correctly. Overall the sound of the P90 is a lot more compressed. It sounds like you would activate a compressor pedal in front of the amp. I love the P90s for that. Someone in the comment section of my videos described them as „clean and mean“ and I think that this is a really fitting description. But sometimes, I feel like my P90s could use a little bit more top end clarity. This is why I like to use it with a little pedal with a treble control in front of it. Overall the P90 SG has a lot of twang and telly-type of growl. The other SG don’t has these kind of flavours. She sounds really aggressive, which I really enjoy. She has a lot of midrange, especially lower mids. And she also has a lot of clarity on top - T-Top pickups are known for that. My pickups are from late 1965, so they don’t have the T-stamps in the bobbins. But they have the orange enamel poly wire and are technically identical to the later T-Top Pickups. I think they sound phenomenal. They react beautifully to your playing and have a lot of dynamics. Much more than the average modern day Gibson stuff. I really enjoy it. But I do enjoy both guitars. The P90 really shines if you use lower gain settings, the 69 can handle both.

Awesome playing dude! To me 5w mode is the best! It still stands up with a drummer and you have much more saturated and usable tone!
Thanks!

That little thing sounds glorious. That, and a mini Jubilee (crunch channel) covers all the territory a grown boy needs.
came here for the amp but stayed for the KILLER playing!!
Awwwwwww thanks! 😳🥺
It's pretty interesting how similar the SV20 and Origin series are.
I really like the way my Origin 50 barks as well. they both sound really nice.
They are very different in schematic topology and soundwise as the result.
I have both amps too. I feel the sv20 is in another class.

@@BlackDogOriginalThat could just be down to using different speakers. I have a Celestion Alnico gold and Harma tubes in my Origin 20c and its now a totally different animal.
@@BlackDogOriginal yes, the SV 20 sounds much warmer and organic

Yeah, it's the same with my '79 JMP 2203. And the SV20 behaves really different from the 1987x I had years ago. But I like it!
Real question is how you can play a sv20 in your bedroom without bleeding ears
My ears WERE bleeding 😂
I thought that was the point?
The same way I play my Origin 50/2x12 V30's in my kitchen.
With bleeding ears.
Easy - a decent attenuator.
But... bleeding ears is part of the Marshall experience, even at 5 watts, not to mention 20.
Stop being a baby
G12m and the cab sounds great! Classic!!!
Amazing tone ! What is the neck pickup? Gibson p90 ? Thx
Thanks! Yes, it‘s the original P90 from 1968.
daaaaaaaaaaamnnnnnnn

This amp is dream come true. Marshall ought to do the Studio 1987 , please 🙏 😭
I really hope for a proper studio version of a JMP 2203. The SC20 sounds nothing like a vintage 2203 🥺
Amazing playing. You have the touch and the ear.
Thank you so much!
Sounds good to me! I have a hand wired Plexi clone and I think the voicing of those Marshall reissues is actually better from the demos I’ve heard. I only payed $700 for a non pcb version though. Doesn’t say Marshall but I can easily mod it.
Yeah, if your amp is handwired, modding should be fairly easy :-)

@@TimMilliken Yeah, I wish it had an built in Loadbox with IR Loader, kind of similar to the Revv D-20
Sounds awesome
@@s.ri.1020 thanks!
Definitely yesII 😍
That guitar is also something special. I also have an SG Standard P-90. A newer one though
It acualy is a Plexi, just a low wattage Plexi,
I think the circuit represents the early-70s-metalface JMPs, just as the 1959SLP. The 1959HW is more like a 1968-model
@@Guitarjosii as close as you can get witout Hand Wireing
The sound of that guitar!!
P90s are special 😊
@@Guitarjosii *Those* P90s are. They vary pretty widely over the years.
@@ポールの赤テレ Yup, you‘re probably right :-) These are the stock ones from ‘68
YES it does!
The SV 20 comes close to the 50 & 100w versions but that's all it does...
I had the 1987x - and the SV20 is a very different animal. I like them both.
My Plexi 20 arrives tomorrow 🎉😅
Congratulations! You really should demo it :-)
What a fantastic tone. I’d love to hear it with, single coils (Fender) and Humbuckers (Les Paul) my guitars
Thanks! I already have some videos on my channel with humbucker equipped guitars :-)
@@Guitarjosii I’ll check them out 👍🏼
Well I guess I'm buying a pair of Greenbacks for the SV212 cab! This sounds great and the playing is great!
Thanks! Greenbacks are always worth a try. You can try the G12M65 Creamback too. Thats what I am normally using with the amp.
@@Guitarjosii ok I do have one 8 ohm Creamback I may try out, just need to load it in a 1x12!
@@bgingras05 You really should. I habe one in my 1x12“ too. I have a video online with my 1x12 and the SV20
