Hey all. I currently have a SWR working pro 400. I also have a GK MBE 2x10 and a GK MBE 115. I like my sound, but want more warmth. ( my opinion of course) but the best sound I ever got from my guitar was an Ampeg 8x10. And a SVT 4 pro. My cabs are like 500 watts. I direct in mostly but I'm looking for a warmer head, and my mind goes to Ampeg. I'm looking at the SVT 3 pro and the SVT 7 pro. I just don't want to damage my cabs. Thoughts on what sound I can expect, and which one I should go for?
