Marshall JVM

Any of you guys tried it yet? Its the new 4 channel, 3 mode-per-channel all-tube marshall. I got to try it today with both an epiphone les paul with gibson pickups, and a schecter with duncans for quite a while before my guitar lesson.
The tone is actually really good, the three modes of clean are all noticably different: the channel gain knobs actually work in the first two clean modes to add warmth and thickness to the clean tone without really distorting it. In the third mode of clean, the gain is bypassed and the amp is set up like an old master-volume marshall. The crunch tones are nice and well...... crunchy, with again, three different flavored modes. The overdrive 1&2 channels give about as many flavors of mid-high gain you could ask for in a single amp, although i did not have time to explore them in depth. Since i was not playing at suitably marshall-y volumes, they were not as awesome as they could be, but sounded great, especially for a 100 watt head at that low of volume. If you are looking for an incredibly easy to use amp with a lot of different good tones, check it out.

On the more negative side, in the short time i spent with this amp i got the strong impression that the build quality is not exactly what you would expect on such an expensive head. I know all the MIDI and electronic gizmos are expensive, but if I was Marshall I wouldnt expect any gigging musician to pay roughly two grand for an amp that has a couple knobs that feel so loose and flimsy i'd be afraid to breathe too hard on them. Maybe this amp just had some bad knobs in it, and it is no indication of the workmanship in general, but i would scrutinize this thing pretty carefully before buying one at that price.

In short, its a pretty kickass amp with some possible quality control issues. give it a spin and post what you think:headbang:
 
Re: Marshall JVM

i was never a Marshall fan until the JVM; it's my current indulgence, sounds good with my Ibanez/ Music man/ Gibson/ Fender/ ESP.

although there are gobs of gain in the OD channels, i still boost the amp with a drive pedal (Ibanez TS7/ Guyatone OD-2 mostly).

i got mine for USD1,300...
 
Re: Marshall JVM

HAHAHAHA

Too funny! I was just about to start a JVM thread, because I tried one for the first time yesterday. Lo and behold, so did you -- guess I'll just tag off this thread.

I only spent about twenty minutes with it at a nearby Guitar Center, just when they opened. There wasn't really anyone around, so I was able to open it up a bit. It was loud enough that the manager hooked me up to a wireless just so I could stand a good 20' away from the cab.

I tried it with a stock Les Paul Standard, which was pretty decent (although it seemed to go out of tune a bit too easily and had that stock pickup flavor). My overall impression of this amp is positive. I like the three modes you can switch through for each of the four channels: CLEAN, CRUNCH, OD1 and OD2.

Spending such little time with the amp, I didn't put in much effort tweaking, but I quickly was able to find a great blues-rock tone in the OD1. I didn't spend much time with the CLEAN channel; I can tell you it got clean, but it was no Fender -- no surprises here. The OD2 was pretty tight, which is nice, because it's easy to get muddy bass at high volume settings.

I played through a Marshall 4x12 with V30s, which sounded great with the volume at or past 10:00. Anything lower than that, and the dynamics and frequency separation didn't shine through very well. This is an amp that likes to be played at high volume.

I dig the Marshall sound, and this amp has a lot of options. Didn't get a chance to A/B it with a JCM800, DSL, non-MV, or any other Marshalls, so I have no idea how close it gets to those tones. I did like the OD channels. Too bad it doesn't come in a more reasonable, non-rock star size like 20 watts; 100 watts is just way too much, especially since you've got to kick up the master volume to get the tightness.

They were looking for US $1,750. That's a lot of clams!

Re: Marshall JVM

I have said it before and i will say it again, the JVM is a DIRECT ripoff of the VHT deliverance. The only difference is that the VHT is built like a fricken tank and sounds amazing. I have to be fair and say i havent tried the JVM, but the design is a ripoff.
Just want to give credit where it is due. That was one revolutionary design that Steve F made from VHT.
 
Re: Marshall JVM

Hate to sound like an ass, but what?? How do you compare a 4 channel 12 mode amp with loop to a single channel amp with no loop and say it is a rip off? I don't get it. I know the VHT's are built like tanks and sound awesome as I had an ST for a while and I've played a Deliverance and loved it. This new Marshall is very versatile and compares favorably with the botique multi channel amps (tonewise) for less $$.

Re: Marshall JVM

But how is the build quality?? At a retail price thats approaching the boutique amps, and Marshalls reputation for spotty quality across the JCM2000 line....I dunno.
 
Re: Marshall JVM

Honestly, it's going to be a while before the reliability thing will play out. It's just going to take some time. Yeah, retail is fairly high, but do you ever pay retail? Don't know where you can get a Deizel or Bogner for close to $1,700, so I don't think it's approaching boutique prices at all. Guys, the designer Santiall posts on the JVM at Rig-Talk.com sometimes. Go check it out. There is also a long thread on the Gear Page about these very issues. I still don't get the Deliverance rip off. Are you thinking of the Vintage Modern instead of the JVM??
 
Re: Marshall JVM

I thought the Vintage Modern was the JVM. Am I mistaken?

Yes, completely. The Vintage Modern is a single-channel amp. That is the one I want. Go to www.marshallamps.com and read up on it.

Good reviews so far on the JVM's. I've heard some clips of the various channels and flavors and I liked what I heard. No matter what the Marshall engineers do, they always sound like a Marshall, and that I like. :)

Re: Marshall JVM

I haven't tried either one yet but from what I've heard about it and the clips I have heard of both, I like the Vintage Modern better for my style. The JVM has some great tones in it, no doubt, but two rows of controls is a bit much for me. I'm a simple guy and I like simple amps. Plus, the Vintage Modern reminds me of my beloved MkIII, just more, well, modern. :)

I'm with you Erik, the Vintage Modern seems like my kind of amp. All that KT-66 goodness, in a simple rock 'n' roll amp with an FX loop for my chorus and delay!.

I was specifically thinking of the Splawn Quick Rod which is in that range. But to your point, the JVM is nowhere near say, a Mojave Peacemaker that will put you out $3K.

Same as any recent non-handwired marshall: the workable side of average. PCB mounted pots etc. Not something I'd trust to tour spectacularly well.
 
Re: Marshall JVM

i tried both the Vintage Modern & JVM- opted for the latter for higher gain applications. if you are in love with the classic Marshall voicings, the Vintage Modern is recommended; the JVM does possess that vintage tingle but IMO the former's KT66 valves are more appealing.

the JVM not only promises some great plexi/ JCM800 voicings; it actually sounds like those. and then some.

Um yeah...I'm gonna have to go ahead and disagree with you there. I've owned both and the Deliverance aint no JVM. The Deliverance is pretty much a one trick pony, good trick, but still one trick. The JVM is about as versatile as it gets and will give all the real big $ channel switchers a run for their money in every dept. This amp is awesome :headbang:

Erik -

Don't know what your style is, but I will bet after you play both and realize most all of the VM tones are in the JVM, you would go for that. Very simple amp to use - it's 4 channels, each with a volume, bass, mid, treb, gain ~ thats why there are so many knobs. Once you set it up you just forget about it. Killer amp

I hear ya, but in my last post, I mentioned that I'm a simple guy. Sure, it seems simple enough to get things dialed in but when I say simple, I mean 1 or 2 channels max, reverb (maybe), and that's it in the amp. Heck, my JCM900 MkIII is a single channel amp with switchable master volumes. That is my ideal amp. Add a phaser and wah here and there. I use my guitar volume and fingers to do the rest. :) If the Vox AD50 wasn't as simple as it is, I wouldn't have purchased it. More than 4 channels in a head is just overkill for me.

I listened to all of carlygtr's clips one day last week. There's lots of sweet tones there, no doubt about it.

Oh, my style is in the area of Ace Frehley, Richie Sambora, Mark Kendall, Van Halen, and a bunch of other influences all mixed together.

I'll agree, the amp is overkill. They could do a JVM Jr. at 50 watts with just the clean channel and say either OD1 or the crunch channel with its modes and be just fine. I am using all the channels though and finding good stuff in each one.

Glad you found those clips of Carls. The Greazygeo clips are a good rep of what it does in bucker equipped guitar...

Here's another with a Les Paul. Guy said he's got serious wiring and grounding issues in his apt. - that's the noise you hear
