No offense taken. (I just sometimes find less-than-serious responses to posts on this BB - think we've all found more of that than we'd like...).
Yeah, EQ on tube amps would be part of what I was talkin' about - like where to set the presence levels to shape tones, especially on the British amps (I think
the JTM 45 model on the V-Amp is VERY convincing), or cutting back on highs when using the dual rectifier models. It's stuff you learn on the amps that help you when you're trying to simulate their sounds on boxes like the Pod or V-Amp.
I think anyone with an ear will get good results, but having played different types of tube amps (with lots of cabs and speaker combinations) gives you a great reference point. My point was, that someone without that experience may be missing something and may not be giving the unit (V-Amp) a fair review, and is probably being overly critical of its noise floor. (Most of the amps I've used were pretty noisy mothers, especially when pushed for gain with single coils under stage lights.)
If someone doesn't have much time on tube amps, then they'll have to have an ear for tone. As an example: try to cop Jimmy Page's tone on "Good Times, Bad Times" (which I believe he did with an old, small Supro and a Tele) - it's there; I found it pretty quickly (don't ask me what the parameters were...); or Eric Clapton's tone on "Crossroads", or his sound when he played with Mayall (JTM 45 with the Paul); or Eric Johnson's tone on "Cliffs of Dover" (think most of that was his Dumble and 335 - and the two Dumble models on the V-Amp are pretty good, considering that probably no two sound alike).
If you've got a picker whose tone you really admire, pull one of their tracks up on your monitors (or through the V-Amp's Aux In jacks - great idea!) and see if you can cop it. It's good to know what kind of pickups and amp were used, but let your ear do the rest. Forget the effects until you've got the tone (you may need some compression to shape the tone, but most over-driven tube circuits do that anyway, so if you're working on that kind of sound, don't compress too much, if at all). Apropos compression, a lot of players will compress the guitar signal before the tube amp (i.e. pre pre, ya know?), which doesn't allow the tubes to do the "musical", overtone compression that makes tube amps so sweet.
This has gone on too long and probably hasn't contributed anything to the BB. Hope it gives someone some ideas.
