NAD: Marshall JVM 410h

Re: NAD: Marshall JVM 410h

Still happy with mine! Mine is a combo, and whilst I want to try to switch out the Vintage 30 at some point (there is that typical mid-honk that I find to be a bit too much), but is still ostensibly a Vintage 30 and Heritage Greenback (the wattage ratings are slightly higher, and nobody seems to know if they are OEM speakers or just relabelled. Unfortunately I can't answer any of your other questions, since the two-channel version lacks most of the channels you ask for, and it seems like we occupy rather different areas of effectdom. That said, you don't really need OD pedals with the JVM, since you have several distorted channels and even two switchable master volumes.

Do you use the G-System with it? Between the MIDI switching of the JVM, Effect Loops of the G-System and on board effects, it seems like a compact and powerful setup. Have you had any issues with the G-System and JVM from a noise standpoint?

Re: NAD: Marshall JVM 410h

Noise has been fine. A lot of people complain about the noise in the JVM, but my experience has been that this is primarily a problem for bedroom players, and that the problem goes away once you play with actual people.

I will say, though, that setting the G-System up properly with the JVM is a pain. The one problem I have with the JVM is the design of the parallell fx loop: it doesn't do 100% serial no matter what. This design was replaced with a series loop on the Satriani, and it is possible to have the loop on normal JVMs to work like that as well. There is another series loop on the JVM, which is intended primarily for choosing between different preamps. For that reason, the level is well above "line level", and will easily cause clipping with the G-System. I use a Morley effects-level corrector to fix the thing. Oh, and I also have to run a buffer before the G-System to avoid an unfortunate impedance mismatch. (This, for the record, will not be a problem with the last generation of G-Systems, where improved buffers were added to the unit itself.)

So there are a couple of things involved. The good thing is that once everything is up and running it does everything I need it to do, and sounds excellent while doing it. I would actually argue that this is a far easier rig to troubleshoot than most pedal rigs, especially ones that involve the fx loop.

Re: NAD: Marshall JVM 410h

I see, thanks! So a Satriani and iB modified G-System solves all the issues that one has when just plugging a standard G-System into a stock JVM. Alternatively, knowing how to deal with audio issues with correct levels, buffers, etc. works as well.

Can you clarify above “choosing different Preamps”? You mean to combine with additional preamps or to use with additional power amps?

As far as I can tell, a Satriani and an iB-modified G-System should work very easily together, although I cannot say that I have ever tried. A ground loop breaker might still be needed, but probably no more than in any other rig.

Regarding the series loop, I am sure I've read somewhere that Marshall intended it to be used primarily for connecting different preamps to the power amp, and that they therefore put as few components that might colour the sound into it as possible. It will work fine for sending the preamp signal to other power amps, or to have a switcher choose between different preamps. It will, of course, also work for anything else, given that it can handle the signal level.

Anyone else still using the JVM series?

Re: NAD: Marshall JVM 410h

Great choice,in that JVM, that's one heck of an amp.

Re: NAD: Marshall JVM 410h

I know this was an old post but I really dig these amps! I got my used JVM410H a couple weeks ago and I'm super happy with it. It's so versatile but it shines on the OD channels imho.

Great amps!! I still have mine.
