The JVM Is Mine Now & Advice For Others

i questioned whether the JVM would be much better than my DSL 100. after bringing the new one home, cracking open the box, and playing non-stop for hours that day and the next, it was pretty much just better overall.

now for the results...

i've heard a couple of people say the JVM is kind of sterile, but that's so not true. it's still got a mean marshall grit. this is probably because it's much more articulate than the DSL. while the JVM is better than the DSL in sound IMO, and i guess circuitry - etc..., the DSL is still pretty ****ed good in my book. the DSL has a terrific tone and is perhaps a little fatter sounding at first, but then you realize that it's because the JVM is fat enough, just more articulate.

the JVM is smoother sounding than the DSL, but without that stretchy kind of sound you get with the DSL. it's more refined - maybe not what you would expect from a marshall with EL34s. i really wish i could afford both because they just sound different, and both are good.

the controls on the JVM seem very responsive. with 4 channels, it might seem like overkill, but there's a reason. there are three basic amp tones the JVM offers the plexi, jtm45, and jcm 800. on one side, the amp achieves (this being said by someone who's only played a plexi once or twice) a really great plexi tone. switch down to the second channel and it's more like a jtm45 (from what i was told, but i never played a jtm).

now on the 3rd and 4th channels, it's jcm 800 all the way. you can get a lot more gain though. now here's where i think people go wrong...

these are basically two kinds of jcm800 tones. one is naturally more mid heavy and the other is more mid-scooped. some people complain that the amp can get thin when you roll off the gain, but that's because you have to also adjust the eq. this amp is not easy to use, but understanding the fundamental function and build of the unit (of course you must read the owner's manual) is really key to building a great relationship with this amp.

i used a strat equipped with alnico EMGs and another with dimarzio virtual vintage solos. the EMGs screamed like never before and yielded some of the most amazing metal tones i've ever achieved. the virtual vintage pickups with moderate gain settings crunched and squealed like never before. super saturated tone even at low gain settings. i was very impressed. i also came to the conclusion once and for all that passive pickups are superior in tone and can't get any better with a great amp like this. i've noticed over time that great amps seem to expose the flaws of active pickups. active pickups get dirty easily and are perhaps too responsive at times. i find myself doing a lot more gain and eq adjustments with active pickups. then again, it may just be personal preference. anway...

i'm sure someone will be grilling me for saying this, but i venture to state that the JVM offers the classic marshall tone and then some. it's a little smoother than i expected, but i can live with that. it's very organic and let me tell you how good the sustain is. oh man, i can strike a note, have a cup of coffee, and it will still be ringing when i come back. what a great amplifier.

you may have wondered that with such a great amp, what will you do with your pedals? all i can say (i don't care who might disagree but i know first hand) is that this amp is unbelieable with pedals. it pushes so easily that you can achieve such nice round tone with an overdrive pedal or a slick crunch with a distortion pedal.

another plus to the jvm is the clean channel. i personally have never heard such a great clean channel on a marshall amp, and i normally think their cleans sound cool. the jcm 900, i thought, had a really nice clean tone but this one takes the cake. what a monumental improvement since the DSL/TSL series of amps.

like i said before, this amp is not easy to use. it's imperative that you read the owner's manual before operating the amp because it tells you how the amp was meant to function and how to dial in the controls. it's not a great manual by any means, but it does have some fundamental information you need to know to successfully operate the amp.

the eq, by the way, is much different from my DSL. with my dsl, it was pretty straight forward, but with my JVM it's not. also, each channel seems to want its own eq settings. i usually leave the eq settings the same for everything, but i realized that this amp you really have to shape the tone.

well i'm no amp expert by any stretch of the imagination, but i hope i have offered some valuable information for any of you who are considering this amp. if you are considering this amp, then you've already wasted enough time. just go out and buy it because it is everything you would expect from marshall to make up for the TSL series. personally, i prefer it over the vintage modern because it's so versatile and the gain is ultra smooth if you want it to be.

i don't normally put the reverb past 9 o'clock anyway, but i always planned to get a good reverb pedal when i decided to go with this amp.

good question though, so let me give a note on the reverb...

i don't think marshall intended the reverb to be what people would normally expect from a built-in reverb unit. i read something, somwhere, that it ws really to emulate the kind of reverb you would get in a recording studio or something. i would have loved real tube reverb, but then again i'm happy to get one new for $1400. it's really not bad at all when you think about it.

Check out Tech21 RVB Boost. Few months ago guitarplayer.tv had some samples from NAMM 2007. Digital reverb in a Marshall head ..... I am getting old, I just cant accept it under any rationalization ...

ok thanks for the tip. as far as the digital reverb, just don't use it. from what i've seen, this amp loves pedals. maybe a good reverb pedal through the effects loop will sound great. i haven't tried yet... then again, i hardly much reverb.

there is one exception to my pedal statement though. i really expected more from my tube screamer than i got with this amp. the amp is very smooth, so it didn't have the really cool kind of effects i got with my DSL. i used to use my tube screamer to smooth out my distortion pedals or amp distortion, for feel, or to put the slightest grit in my mesas clean channel. now it seems rather useless with this amp.

on the other hand, just about any overdrive or distortion pedal i've tried sounds spectacular. one nice suprise was my metal zone pedal. it was more like a novelty before, but it sounds so good with my jvm that i'm going to keep it on my pedal board.
 
Re: The JVM Is Mine Now & Advice For Others

if you have 2 distortion channels, each with three modes, why the heel would you need a distortion pedal??? I'd sell mine and get something cool like a tremolo or flanger or delay!
 
Re: The JVM Is Mine Now & Advice For Others

I just received mine a few days ago, and my distortion pedals haven't gotten used much since. I do use the Fulltone Fulldrive 2 to boost for solos with a bluesy distorted strat tone. My BB Preamp and RC booster just sit -- I find they color the tone a little too much of this amp.

This is an incredible amp though. All sorts of Marshally tones throughout. It's going to take me awhile to get everything the way I want it. Right now I could live on the Crunch channel in orange mode all day. The clean channel is very nice too - green and orange with a bit of reverb added sound so sweet.

This is a massive improvement over my TSL, which I thought sounded pretty good.

on man if you only knew what it sounds like with a pedal. i put several distortion and overdrive pedals through the clean channel and got some great tones. the amp distortion is to die for, but sometimes you need to give i a little extra spice. :dunno:
 
Re: The JVM Is Mine Now & Advice For Others

Just played one yesterday, very cool amps. I've played the Vintage Modern before and dug the tones, but there's no doubt in my mind that the JVM was a lot more versatile and could do (IMHO) some better tones.

The cleans sound GREAT pushed. I had a lot of fun rocking the neck pickup on a Gibson ES-339 through it, just full on bluesy bliss.
 
Re: The JVM Is Mine Now & Advice For Others

i was looking at one of these JVM's today... here in Canada they are $1999... pricey... a TSL is the same price basicly....
 
Re: The JVM Is Mine Now & Advice For Others

Good review - glad you're enjoying the JVM. It sounds pretty cool
 
Re: The JVM Is Mine Now & Advice For Others

Makes me GAS even more for one of these babies!

he he, you should gas for one. i think a lot of people haven't given the jvm a fair chance yet so it's not that hot right now, but i think they're going to catch on. the best marshall i've heard yet.
