As stated, I hate its tone. My Hartke 30 watt 8" practice amp i keep at my girlfriends apartment shreds my Ampeg svt-4 pro head and 410 cab on tone.
I have been through the rings, back and forth, and have finally just decided it sucks. I don't know if its the head, or the cab, or the speakers being old, dead, and flat. I wish I could post clips but I don't have a way to record it with any quality what so ever currently. Any of you have a SVT-4 pro and actually like it? I wish I had a different cab I could play with for a week to see if its the head or the cab that's killing my sound.
Take your head to a music store and ask to plug it in various cabs. Try everything. Then you'll know, and if you're not happy, holy shit you're in a music store and can try some heads!
I'll assume you've got fresh toobz. Tired ones sound like ass.
