New Marshall JVM410HJSB Joe Satriani Sig Head released

[King Guitar]

Got a call from my guy at Marshall saying the new Joe Satriani JVM head is shipping soon.

I didn't hear too much about this other than it was a totally reworked JVM to Joes specs.

Any of you guys seen or heard any reports on this amp?

Price point looks like $2549 ish.

Offhand I know the clean channel was reworked, that OD2 is now a copy of OD1, and that the 4 reverbs were replaced with noise gates. I posted something about it a few months ago, let me see if I can find it.

edit: found my old post about it.

No reverb
4 noise gates
"re-biased" presence and resonance controls.
Gave channel 1, or atleast one mode of it the voicing of the Marshall 6100 (30th anniv.) channel 1.
took away some compression from the sound of the amp.
Made OD2 a copy of OD1

I heard about these a while ago and I'm going to snag a few. I'm not sure what the demand will be, but Knowing Marshall, Id get a few now before they get backordered lol! Seems great on paper but I need to hear one in person!
Here is teh blerp from Marshall:

Marshall’s R&D engineers set out to work incredibly closely with Satriani, the latter having a very clear idea of how his own Marshall should sound. After various trials and experiments which even involved Satch using prototypes during recording and touring, the final version of the JVM410HJS was signed off and the wheels for UK production put in place.

At first glance, the JVM410JS may look familiar. Taking a more detailed look (and listen) though, will make you realise just how different this amp is from its stock counterpart. So, how is the JVM410JS different from the JVM410H?

Firstly, and probably most notable is the fact that the four Reverb pots from the original JVM410 have now been replaced with Noise Gates; four Noise Gates no less, one for each channel and each with their own threshold. Another visible change to the front panel is the addition of a ‘Mid Shift’ button that can be used for both OD1 and OD2 channels, shifting the mid character of the sound to that of Joe’s specification.

Tone wise, the amplifier is very different; The Clean channel is based on the aforementioned 6100 when on the green mode, with the orange and red modes being hotter variations of that tone too. The Crunch channel takes the original JVM410 crunch and adds some of the popular Marshall ‘AFD’ circuit to it, and the OD channels are now both voiced identically, based on the JVM410 OD1 but with the gain scaled back slightly and a smoother transition between modes. The mid shift button determines the difference in mid character between the original JVM410 OD1 and OD2 tone, moving the mids from around 650khz (Mid Shift off) to around 500khz (Mid Shift on).

The rest of the JVM410JS plays out in familiar territory; the amp is still powered by EL34 valves, there are two Master volumes, the supplied footswitch enables you to switch between Channels, Modes, 2 Master Volumes, FX loop and now also the Noise Gates and Mid Shift. There’s also full MIDI implementation on the unit



All the best!

Watched the videos that Brad posted and Joe said he wants it in that Purple tolex that the 30th Anniversary models came with. That would be cool!

Gary Holt told me as soon as they are available, he'll be switching to those from the JVM210s he's playing now in his Slayer rig....

 

[skoora]

Spec wise what he talks about sounds great but the problem is I've never liked his tone.

 

[DoomBuggi]

I imagine some one will go and tweak that amp a bit.

 

[carlygtr]

This amp will kick ass. Very logical mods and additions will make this a winner and one I'll probably want to own!

Agreed, having spent a few years with a 410, the changes mentioned should improve the overall tone with less compression and a more open, touch responsive tone. I do like the reverb on the old one, I kinda hate to see it go. I would take less comp in a second though, they are just a tad too compressed at some settings. I did not have any issue's with the loop, I thought it was decent as is
Cant wait to hear one, I'm interested

 

[verderacer]

I never liked the compressed tone of the old amp and I glad Joe got it out of there and put in the noise gates instead of the reverb, which to me did not sound very good.

I look forward to hearing and trying one and get a personal feel for it.

The real question is, will it sell. At $2600 I can think of other amps I would rather have.

I could see you liking the changes, even I do not have much use for OD2 due to the amount of gain, using OD1 "2" could be a total solo boost with volume as well. IMO the crunch channel is fine as it is and the clean changes sound cool.

The only differences between the OD1 and OD2 on the original are the coupling caps after gain stage 1 (3n3 and 1n respectively), 1n and 1n5 treble peakers across the 470k/gain pots, and the slope resistors (33k and 47k respectively) in the tone stacks. Otherwise they share the exact same circuitry. The 1n in OD2 cuts some bass a hair, the 1n5 "peaks" some high mids a little more, and the 47k shifts the mids in the tone stack a little bit, otherwise they have the exact same gain.

Some of it sounds good (like ditching the reverb for noise gates) but I like the Fender-y clean channel as it is on the JVM410H. I can't remember what the 6100 cleans sounded like. I kind of liked the OD2 tone as well with the emphasized low-mids. It's good for stoner/doom tones. Hopefully the mid switch on the JS will sound like the OD2 does. Having two OD1 channels doesn't make that much sense to me.

I was thinking the same thing. I have owned stock JVMs, and the best thing about was the clean channel. I am sorry to hear they messed with that.

We have 2 black ones and one of the limited edition Blue Half Stacks in bound if anyone is interested in getting one.

I hope this works out better than things with Peavey, where he started with a XXX, and made them less cool!

 

[carlygtr]

He's been sounding real good in Chickenfoot with these heads. His tone on all the Montrose tribute vids is excellent. The clean ch in those old 30th ann heads was very good too, IMO.

Satch is noted for that DS-1/ Basswood nasel tone which is a product of that combination.
Just don't use that combo and you'll avoid that nasel tone!

Anything with built in "noise gates" scares me but....I'm told I should take up drums anyways so...WTF do I know?..

I thought the JSX was the best sounding Peavey, more open. I do really like his Chickenfoot tone. These amps are meant to be played loud. He has said he dimes the volume.
