Hi all. I am patiently looking for a deal on a used amp head scouring locally mostly. I think I have decided to look for a hybrid with a tube pre and SS power section for the obvious reasons that make them popular. I don't have a cabinet yet, but that will probably be determined by the head. If I buy used I want a company with a good reputation for reliability and service. 3-500 watts $500 or less. I like a good mostly clean with a hint of overdrive rock tone. To me (like most) the SVT is the gold standard, but that is not set in stone for me. GK? Hartke? Ashdown? Aguilar? Thanks.
