I just picked up an aguilar gs 212 as the first step in building a new rig. I am now in the market for a head or power/pre. What I get will Depend on how much $ I get back from trading in my old combo (a trace elliot 1215 if anyone's interested). My band does classic rock/covers with some psychedelic type originals (1 sometimes two guitars, keyboards, drums and me). I do not plan on adding another cab. What are people powering their gs212's with? What might people recommend with this cabinet? Any input (pun intended) would be appreciated.
