JVM 410H - some discoveries; early days with it

Mostly positives so far. Everything seems to work okay, all 4 channels and the 3 modes of each, both masters and all the BMT, the reverb, loop, footswitch. And this thing can produce a heckton of damn fine tones. Like, everything from crystal cleans to seriously high gain - almost all of it usable, surprisingly.

The only thing I haven’t tried using is the other [preamp out / power amp in] loop.

The other loop (which I do use) is set to +4dB, which it apparently prefers. No issues with it, despite the numerous things I’ve read online. Just goes to show, hey. :) But nope, not for me - been running all kinds of effects in there: chorus, flanger, delays, reverbs, etc.

This amp deserves a better rep, IMO.

However…

There might be an issue with relative volume levels though: switching from some modes to some others, there’s a significant jump in volume. Not with all mode switches, however. And I don’t mean Clean Green, which while annoying (i.e., channel volume control need not apply), I’m aware of and can adjust for. Will have to double check, but I believe one of them might be Crunch Orange to Crunch Red. Can’t remember the other(s).

That, and I think at least one channel/mode setting is noticeably darker than the rest. Again, Crunch Orange is - I believe - the one, or one of them.

Definitely need to confirm which channel/mode setting(s) are potentially iffy, I know. Away from the amp right now, but felt like asking anyway. :p


How much of this seems normal to y’all JVMers out there? Could one or more of the tubes be to blame? I did buy it used…
 
I got my 210h last week-ish. Feature and functionality rich to the point of overkill tbh. Tones are STELLAR to my ears.

I cleared all the presets and cleared footswitch config to sort of start from scratch. Without presets; I have zero idea how they expect you to switch from clean/crunch to the OD channel with consistency. You would need to do some serious compensation on one channel or the other and even then; I would not trust using it that way live at all. As a stay on a single channel and sprinkle drives on top as needed; ooof! Congrats!
