hey guys, I have an Ampeg svt-3 pro and well im not entirely happy with it.. I am wondering do you guys think I should trade to for an SWR 550x, i want a punchier sound and ive tried and i think i liked it more.. maybe im crazy, or perhaps i could just change the cab (SWR WM 410 to an ampeg svt 610) what do you guys think? also what about those bbe 383's, would it be a good investment for a preamp? thanks
