School me on the JVM410 and JVM205 heads

[BABMusic]

Okay, so I've never played either of these amps. So far, some people I asked about these heads have told me they sound unnatural or artificial. Kyle Bull's video, which I just watched today said he wasn't all that impressed with this amp, and he's obviously a big Marshall guy. Said he couldn't find a sweet spot where it wasn't too bright or too dark. Some have also said that the 410 is the way to go because the OD1 is the best high gain tone and that OD2 is actually more like a Mesa/Marshall thing. Is it true that the 205 head is the Mesa/Marshall tone only on overdrive mode? That would probably turn me off. I already have a Mesa tone that I love (Mark IV). Mainly, I just want a more authentic high gain Marshall tone similar to my old DSL100 I used to own. Cleans are not so important to me because I already have that covered. Also, are these things a pain in the ass to bias? I want to be able to do this myself, and I know these do not have the external bias knobs.

So, school me on these amps.

I do not think it sounds like a mesa ever . It will never remind you of your mark iv . Has both . Get a jvm 410 so you have all the options

Been on a bit of a Marshall kick lately, so happy to share my experiences.

Overall - what the JVM gains in versatility (it can cover A LOT of ground with the 4 channels and associated options), it loses in overall rawness of tone. I found my old JCM2000 DSL 100 to be more raw/open/aggressive, and you'll then get even further toward the desirable Marshall 'kerrang' with a JCM800 (I currently have a 50 watt 2204 I absolutely love). The JVM, comparatively, is more compressed, and can get buzzy at lower volumes.

Another thing to ask yourself - what Marshall tones are you really looking for, and what kind of amp approach most inspires you? The JVM has a VERY wide range of gain built in, going from plexi inspired all the way to very high gain/modded territory. A JCM800 won't get close without a boost. For me, I've been finding a lot more inspiration in the simpler amps. With many options/channels like the JVM, I find myself tweaking/testing options, which is less inspiring to actual playing. In comparison, plugging into a JCM800, I cue into its vibe, and play accordingly, adding a pedal or two if I want to expand what it's doing. Simple, to the point, and 'the sound'.

All that said - in a loud/band mix, these nuances are further lost, and a JVM will absolutely offer a wide range of Marshall inspired tones (exactly what it was designed to do). They're great amps, but if you're looking for the most authentic/pure Marshall tone, you're better off looking at their simpler/more traditional options.

My opinion, YMMV. Good luck on the hunt!

I think it sounds great; I have a JVM410H and it covers all the Marshall tones I'd ever need from JTM/45 to JCM 2000. I have other Marshalls / Bogner / Engl for the Marshall / modded Marshall tones I like too;

There's a Satriani version that many say is better, never tried one.

If you know what Marshall sound you want, you may just want to get that amp; but if you want a wide range of Marshall tones, the JVM410H does it. IMO

Posted a very detailed review of the JVM 410H a few months back. You should take a look. Its a great amp.

Marshall JVM410H Review

My two main amps are the Koch Supernova and Diezel VH4. Both are rich and hi-fi sounding boutiques that are amazing at what they do. About 18 months ago I acquired a limited edition jubilee silver JCM2000 DSL half stack that I was enjoying. Shortly after the fires hit my town (Pacific Palisades) a collector made me an outrageously high offer for that set-up and I accepted. I loved the looks and rarity of that half stack, but I think I only "liked" how it sounded....Really good, but not great. Having the Koch and Diezel, I doubted that I would miss...

It's unfortunate that I cannot play either the 205 or the 410 in my city. I figured the 410 would be the best in terms of options (I love options). But I'm having second thoughts because some people said the OD2 on the 205 is very similar to the OD1, but with just more scooped mids. I actually scoop my mids quite a bit when I play in my home studio (I'm not one of those guys who uses the same settings in my studio as I would in a band). Midrange is essential in a band setting, but not necessary when just playing around alone. But anyway, coming in at 48 lbs and the 205 at 38 lbs, that's quite nice that the 205 is that much lighter. Tube changes would also be a bit cheaper with just 2 EL34s. While 48 lbs is unlikely to give me another hernia, it's still a pain in the butt to move around. But tone is the most important thing, and options. I'm one of those guys who love the Mark series because of all the options. I'm gonna talk to some more people and see where this leads me.

I had a JVM back around 2008 or so. I thought it was a great amp but smoother than those older Marshalls like an 800, Plexi, etc.

I have the JVM 210H. Great amp! I have also played it next to my Mesa Badlander, MW Recto and MKIV as well as my old Marshall jcm 800 2204.

PROS: Can cop a great feeling, hot 800 tone on ch2 green...and do so at manageable volumes!
Responsive tone controls + resonance allow better tone shaping than older Marshalls I have owned (including the dsl 100)
Ch 2 Orange + Red can go from modded 800 to brutal, tight modern Marshall.
So ya....the JVM is a modern Marshall in every aspect and can certainly cop the tone/vibe of older models.

CONS: The mode switches are useful in finding your tone, but programmed switching in a live situation results in crazy gain and volume differences; so each channel you kinda find what works and set it.
The overall gain in orange and red ch2 is too over the top and could use a better taper.
Great modern Marshall....but not a substitute for a vintage Marshall. By that I really mean a plexi or 800. My 800, at volume (key here....these are and were meant to be stage amps after all) has an attack and punch and kerrang that is...well...part of what makes those amps great!

I will also add that i like the JVM better than the DSL's and it isn't really a MESA/Marshall. It still sounds more Marshall in character than even my Badlander and that is a more British leaning Mesa.

Well, been my main amp since about a year after they were released. I've had them modded, had the Satch model and I greatly prefer just the stock JVM 410. The Satch model actually has some good functional upgrades like the Serial Loop, Choke and Noise Gates however the tone is muted. For me they neutered this model tonally barring the Crunch channel. But that is what Joe wanted.

JVM sounds great with pretty much all celestion's. My current preference is a mix of V30 and Annis. My main touring cab back years ago was just a stock Marshall 4x12 with 75's and it sounded fantastic with that cab. Per Santiago the amp was designed with 75's in mind.

My experience only, other's may disagree. Btw/ I grew up on Marshall JMP's and 800's so that's my tonal DNA.

• Clean - Good. Really good for a Marshall.
• Crunch - Unusable for me. Even with an OD, still really woofy in almost any mode. If Marshall ever updates the amp, need to update this section as they did on the Satch.
• OD1 - This is the reason to buy the amp. All three modes sound fantastic and why it's remained my main amps for close to 20 years. OD1 Orange, hot rodded Marshall, no OD required. I live on this channel for both rhythm and lead. Have a simple volume boost for leads and or my guitars volume. OD1 Orange is why I've stayed with this amp and will continue to do so.
• OD2 - Another great channel with even more gain. This will get you a more modern sound. No not going to do Mesa etc... but this was Marshall's attempt at it per Santiago the designer. Just pure high gain. This is the channel they put on the 205 and 210. OD1 is not on those amps. Why? Who knows. But this alone has kept me from buying the 205 head.
• Loop - Works fine for me but would be better if it was just a serial loop like the Satch model. Don't over think this, turn the Mix all the way up.
• Resonance - Use it. See way to many people backing off here, don't. Find the sweet spot with the Res up and the Bass on the channel.
• Reverb - Useless for me. If they ever update it should just make those Noise Gates ala the Satch model. That said, to this day I still do not use a Noise Gate.
• Master Volume - easily one of the best high gain bedroom amps out there.

What can I say, even with their faults I love this amp. However the platform is approaching 20 years. It just needs some simple updates. Credit Marshall though, as much as they've lost the plot now that group of designers that were there with Santiago years ago put out some great amps and reportedly shelved alot of amps that should have seen the light of day. Any amp I've owned in the interim has just been for fun, I don't ever see myself leaving this amp unless Marshall updates it. I'd also like to see Marshall do a Synergy JVM module, do that and I'll buy that. Really what Marshall needs to do is just unwind the tonal changes of the Satch Model barring the Crunch channel, put them back to stock and re-release that as the updated JVM 410.

I always pass this along as well, great chat with Santiago the amp designer and what he was going for. Let's you know the platform the JVM was based on. Click Here.

So, first thing don't watch Kyle's video, one of the worst. Not sure why as I generally like Kyle's stuff.

Find Rabea's video's on them, much better realistic representation of what the amp sounds like. This IMO is the best representation of the JVM from my experience of owning them.

 

[nightlight]

I've had two JVM410s. I think they sound great, but I was downsizing, so the second had to go as well.

Here's a couple of clips I did.

 

[jabps]

Not with the Tube Amp Doctor Bias Master.

 

[jasonP]

This is one of my favorite clips that Ola has done of this amp and the Rabea is awesome as well. I was turned on the JVM410 from this forum a year ago to get a channel switching amp that could do the tighter more aggressive modded Marshall thing without having to use a boost to get there. It can do everything from clean which I think is really great clean channel for a high gain amp, good crunch channel really needs to have C223 - 22n changed to 2.2n on the control board to fix the to much bass or woofyness on the crunch channel, to OD1 has that modded Marshall thing going on and the more aggressive OD2 channel is awesome as well. I don't find this amp any more noisy then any of my other high gain amps. Not a fan of any on board reverb on any amp to bad Marshall doesn't update this amp with a gate instead. I think for $2K it is hard to find an amp with as many features and great sound.

Agree with almost everything here

 

[BABMusic]

Not with the Tube Amp Doctor Bias Master.

I have a Eurotube bias probe that makes it super easy, so all I need to do is find those two little bias knobs, which I did see a youtube video on where they are. Looks no harder to bias than my Friedman.

Funny you mention that because his video was one I did watch. He was not a fan of the JVM410 and that did give me second thoughts on the amp.

Anyway, I'm just gonna go with the 410 this year. Not sure when, but sometime in 2026 and will report back when I receive it. Too many people said the OD1 is the best channel, so the 205 is always going to make me wonder if I missed out.

 

[BABMusic]

Yeah, I noticed a lot of people mod the 205 to make it sound like OD1. I'm not competent to mod an amp, yet.

Some people also mod the 410 as you can see in this listing. This person added a plexi cap and a negative feedback adjuster switch.

It didn't sound good on Kyle's video. Maybe the amp was jacked, maybe Kyle was jacked that day lol. No clue.

Really, the best starting point for that amp in my opinion is put your Bass, Mids and Treb at noon, work your Res and Pres and then tailor the EQ controls. All of mine are pretty much at noon still. Bedroom levels I crank the gain up but live and in the studio, backed off a whole lot. Set your Masters and then use the channel Volume for your control. And no, cranking the Master will not make the power amp section work harder like it does with some amps.

There is a mod for the 205/210 that can make it sound like OD1, one of the amp guys here probably knows more about that than me. See below. There's also a Boss GE-7 Trick you can use as well but I cannot find that for anything now. Years ago there use to be a whole chat site dedicated to the JVM, was a ton of cool info there and I thought I had a screen cap of the settings.

Ultimately the 410 is alot of amp and having both OD1 and OD2 is totally worth it. My recommendation if you do buy a 410 and start modding, buy it stock and take it step by step. I've owned 4 of them. My first stock that I still have, another that was modded with choke, NFB, Plexi which was sold. The Satch model, sold. And another stock 410 I got from the same friend who sold me the modded one and in turn eventually sold back the modded one lol. I currently have two stock 410's which I much prefer. Again, I'm on OD1 Orange most of the time but it's fun having the extra high gain options.

Flipside, it's still an amp and like all amps it'll either work for you or it won't.

Here's a link to the OD2 to OD1 mode...Here.

I have talked to a few different players in LA as well as a couple techs that perform mods and the general consensus is that outside of a choke and upgraded transformers...Most seem to prefer the JVM410H in it's stock form. And I have yet to have anyone tell me that the Satch version sounds like anything other than a JVM suffering from Low testosterone. I'm leaving the one I have stock. That said, if somebody like Ground Zero (@RedPlated) ever starts modding the JVM specifically for modern metal (slightly tighter and more aggressive voicing), I would likely acquire another one and have it modded for that application.
