I have a Ampeg svt-4 pro and a Ampeg 1X15" sub cabinet. when I was playing in a band I used to play on a Trace elliot 4X10" cabinet and the 15" cabinet. I played in a nu-metal-like band with one 7-string guitar and drums. The guitarist had a Warhead(?) Dimebag signature amplifier, so it was some pretty heavy **** that came out of that guitar... I felt that my sound was very low. Is this the cabinet or amp's fault - or maybe the warhead? What Cabinet would fit my amp?
