I am finding that the Xotic AC Booster has way too much of a mid-hump. I think it really takes away from the top end and does not sound open at all. Is it too compressed? Its not dark but I keep turning the treble up??? The REALLY like having the separate bass and treble controls and this pedal sounds pretty great at home in low volume situations but Anybody have a similar opinion? I have heard about different versions and possibly mods. Any info on that?
