I've just about given up on my SVT-4 since I think it sounds pretty horrid IMO. I'm looking into a Mesa 400+. I know the Mesa is rated at 400 watts and the SVT is rated at 1600 bridged, but is it really that drastic? I've been reading up on the Mesa and people generally don't need to turn up past 12 o'clock. Would I be downgrading in this situation? I have a Modulus Q5 and an Ampeg 810, so don't start making acusations that it's not the heads fault! I'm also getting a Mesa 1516 I found for dirt cheap to see if this helps my problem as well. Power...will I get enough?
