I am tired of my Ampeg SVT-4PRO breaking down. I am also tired of the horrible "service" and "support" I have received from Ampeg and their Warranty Centers. I won't go into the lack of which I have received. If you are curious, email me as I am not into public bashings of companies. My amp recently died again. No, it is not abused or beaten up. I play through the Ampeg PR15H and PR410H and was wondering what other head options there are out there to power these speakers and give me the same volume (if not more!!!) than the SVT4PRO did. I am open to going to a preamp and separate amp as well, but would prefer a head that does it all... Any suggestions?
