Marshall SV20H - First Impressions

Had a blast checking out the Marshall SV20H today.
Total nostalgic tour into the early metal scene with the 20 watt studio plexi. I was really interested to see how it goes trying to work with boosts and eq's in the FX loop.
Thanks very much to Marshall for supporting the channel.

[@jcugnoni]

Great riffage and demo. Sounds great from here. By the way, the reason that the tone stack does not change much the tone in vintage plexi is because most of the distortion comes after the tonenstack, from the power amp. So the tone stack is a pre-distortion tone shaping , like the eq on Mesa Mark amps..

[@TheMetalGamer3356]

I got this a few years ago for AC DC stuff. I had it modded for a MV and just general improvement. Sounds great.

[@pharmerdavid1432]

Beautiful "plexi" type, good job Marshall. I'm leaning towards the ST-20 JTM studio series, because I prefer clean tones, but that one is awesome too. I've gotten the JTM-1 50 year anniversary one watter, and even it can get too loud if it's cranked, I use it with a less sensitive/efficient speaker(greenback) to keep the volume down in the sweet spot. If I want to play louder then I plug into the cab with an Avatar A25 (Celestion blue type). I'm amazed at how much of the JTM sound it gets, even with the little wonky power tube!

[@CPUrafael]

Always some new piece of gear to show off. What is the next thing you have your eye on? Oh I did get a parametric eq and I definitely dig it. I went with a Guptech pPTSD. Almost half the price as the EQFH. From what I can see, covers all the same frequencies. Bonus, it looks fantastic.

[@toraksel]

Amazing, I had no idea a plexi could produce those tones. Any chance you'll do a video comparing and shooting out the SV, SC, and DSL? Would be so cool to hear them up against each other and hear how you think they differ.

[@portuguesebeer5069]

I agree!

[@1thess523]

I came for the Marshall but the Vallely boards were a nice bonus 👍👊

[@corycourtney8923]

Bro has the Zero Converse. I wish I still had mine, but they got destroyed. Tone's sick and good to see the Birb's, as always. Bonus, I learned something about Plexi's today.

[@mourningleaves]

Great tones! The volumes for each channel are more like gain controls than master volumes. Both in where they are placed in the circuit, and how they act. Full volume is reached very low on the dial, usually like 2 or 3, and from that point, they just add distortion. If you don’t jumper the channels and push the brilliant channel to 9 or 10, it mellows out and becomes THE classic sound. And keep the bass low, like 0

[@NateGrzesiak]

MAN IVE NEVER SEEN ANYONE NAIL THE MECHANIX SOLO LIKE THAT. THAT WAS AMAZING YOU NEED TO MAKE A LESSON ON THAT YOU'D BE THE FIRST ON KZbin!

[@michaelholmes9153]

I found the amp loud and untamable but you calmed the beast that the Plexi can be. It nearly approaches the JCM800 in gain which is amazing. Yet you have to do that with overdrive and EQ.

[@flyingrhoads]

Awesome!! Thanks using this Marshall!!! Sounds great. How is the room volume? Is the 20 watts enough for a live band and play live? Cheers from Kentucky!!

It needs a power soak for home use but it’d be fine for clubs and jamming

[@BradRocker]

Certainly a more open vintage tone, but Rocks none the less !

[@steakndcheese]

Would love a dio holy diver video with the boss sd1 using this amp.

[@ale0800]

I bought the SC 2 years ago and now I also have the SV. This amp is a true time machine that takes you to the tones of the 70s and early 80s. I never had the opportunity to use an SLP100, but I imagine it must be very complicated to use it in rehearsals and small gigs, as the SV20 at the 5w position it is already extremely loud. : ) Still comparing the SV with the SC, I noticed that they have some points of similarity, but the SV seems to be more versatile for other styles, such as hard rock or pop, for example. I haven't had the chance yet but I would like to try the mini Jubilee. In some videos I could see that his EQ is very active, allowing everything from classic to modern tones. If you have the DSL, SC and now the SV, which one do you like best? Once again, thank you for sharing your experiences! Congratulations on making rich content!

[@LambChopper678]

Hey thanks mate, I’m sure I’ll end up grabbing a jubilee but my favorite so far is the 800. I like the heavy punchy feel

[@aquilarossa5191]

They have that wild kerrang to the high end that later amps to not have. The low end can get a bit loose and unruly though. Never seemed to bother Angus though. His tone is hard to beat, especially live during the Bon Scott era.

[@dimsoneill]

How those old school Valley's with rails on the door. And now an extra bird. Excellent. Air Force Joey says hi Lamby.

[@metalinsights9664]

This amp sounds so much like classic Maiden. Piece of Mind in a box.

[@lovecraftmusic8717]

If I find one in a store I'll give it a try for sure but needs an attenuator desperately to work properly even with a booster. Maybe the fact that you're forced to involve the power amp by crancking it in order to have more gain and mix the two channels is the magic formula for Piece of Mind.

[@metalinsights9664]

@@lovecraftmusic8717 There's something different about these amps that goes beyond what can be explained by the effect of driving the power stage. For one, they have less top end than JCM800-style amps (which is pretty main lines of amps after JCM800, including, and especially, the DSL, which has a lot of treble that can, however, be dialed out). Second, they have excellent single note definition. If you listen to Maiden's original version of "Sanctuary" with Paul DiAnno, you can hear the first two strings ring out clearly in the mix, which is a good example of that clarity. And lastly, these amps manage to sound overdriven without what I would describe as buzz between notes and chords. They just sound really clean and tame, but also overdriven. The bit that Anthony plays in the intro to his new video is a good example. You get the drive but without the noise part, which is another thing that stands out about the tone on Piece of Mind (e.g., the intros to "Still Life" and "To Tame a Land"). For some reason, these amps have all the good stuff associated with overdrive, but none of the disadvantages, which results in such a controlled heaviness. I also like how incisive the midrange is. Very compact, with a tight, percussive low end, which these amps don't seem to have much of, but that must also be why they sit so well in a mix

[@metalinsights9664]

@@lovecraftmusic8717 One more thing. In the "Flight of Icarus" video, where you can see the four-hole JCM800s that Adrian is playing, it shows that he is plugged into the high treble channel, with no jumpering of the two channels. Perhaps that explains that bright nature of the tone on Piece of Mind (At least I always perceived it as very present and bright, in a good way. Others may disagree.)

[@lovecraftmusic8717]

@@metalinsights9664 corious... For me Piece of Mind has always been a dark warm tone...Powerslave is bright/clear/neutral/balanced by comparison.

[@metalinsights9664]

@@lovecraftmusic8717 I agree. Powerslave is very compact, more ambient, whereas Piece of Mind is warmer and thicker. I associate Piece of Mind with "bright" because of the tight low-end. For example, if you listen to "Where Eagles Dare," the palm-muted pedal notes on the main riff should normally be very heavy, especially with two guitars, but they are not even audible on the album. Another good example is the low-E palm-muted pedal note in the chorus of "Die With Your Boots On." Those palm-mutes should be very heavy sounding, but they are not even audible. I am not sure how Maiden pulled that off, but somehow the power chords is all you can hear, whereas the palm-muted root notes are so inaudible that it is not clear whether they are there at all. This is one of those things that makes Piece of Mind a cut above the rest. Maiden's heaviness is so subtle and classy, that they avoid solutions that any other band would think is an obvious choice. If you read reviews of Piece of Mind, you'll often hear the complaint that it doesn't have enough low end. Which is not true, as the perception of missing low end is there because the guitars are so crisp and so well-seated in the mix, but all the complaining did have the result that the 2015 remaster of Piece of Mind got a serious boost to the low end, both on the guitars and the bass.

[@Paincakes]

Cool video. Which of the SC20 or SV20 is more fitting for metal over all?

[@LambChopper678]

Sc20 is much more modern and sounds heavier. This is old school metal tone where you need to be a little looser and lighter on palm mutes

[@angrytroll27]

The eq in the loop may not work as well because the power amp section is being overdriven

Jel amp is great

[@roncarter2188]

So i bought this same amp new after watching many videos and everyone seemed to love this amp. Well this was a lesson for me and i went against my better judgment and bought without ever playing one personally. I did not like this amp. I didn't like for starters the cleans, yeah thats right the cleans sucked! The overdriven tones were brash and brittle sounding with no bass or ump that it needed no matter the settings i tried. I traded this amp after trying for a month to like it. I built from scratch a 30 watt plexi - my second from scratch at this time. I love this amp i built! Try a amp out before buying one, that was a lesson for me that everyone should follow. This of course is just my opinion and you will have yours.

[@Greg25815]

[@wanik4]

It's like a younger Steve Martin and Steve Irwin joined up and learned how to shred.

[@wootks]

I feel a loop in a non master volume amp like a Plexi is a waste of time. Dave Friedman is intentionally not putting a loop in his upcoming Plexi style amp. Mostly because it will just make things worse. Your experiments seem to match that notion. Similar amps like the EHX Mig50 don’t have loops either, but I think that’s a good thing. Only bummer about these style amps is home players gotta run into a load box or use a Fryette powerstation to get the gain at a volume level that does not piss everyone around you off.

[@aynakotalaga]

Yes! I bought one a few months ago and had to run it with an Origin Effects revival drive in front as my Power Station was on a ship as I'd just moved countries! This amp needs an attenuator. With a Power Station, it sounds glorious!

[@wootks]

@@aynakotalaga Agree. The Power Station is the best way to crank a NMV amp at home.

[@LookingForEntertainment112]

Yeah, I own the Studio SC, SV amd DSL amps. All loud as hell, sound great and definitely long term keepers. The SV is great for Doom or Stoner rock when boosted and EQ'ed properly. But it will still sound like a Plexi! Lol.

How do you compare the DSL with the others?

[@LookingForEntertainment112]

@@cavacofonseca More modern I guess is the way I'd put it. It's a more versatile amp and tbh just killer value for money. The SC and SV nail their thing though and if you're after those tones they're the ones to go for. If I had to choose only one, I reckon the DSL would be it though.
