First post here and i know the Amps are new, I got mine home yesterday and just love it except, the reverb sound thin. I got a new one in the box and compared to the one at the store it is thin sounding not really warm. Both are going thru 4x12 cabinets with V30's so that is the same. It works correctly just thinned out, what I was wondering has anyone ever changed out the reverb tube in say a Stiletto or some thing to darken the reverb.
