Should I get a Head or poweramp with a preamp? I have been looking at Carvin heads , however people say that they overheat and get hot quickly. Does anyone know if this is true? Anyway, I am not sure if I should go with a power amp/preamp setup. B/c this guy I kno has a preamp and effects rack he wants to sell, and I can get them for prob about 100 $ bucks a piece. I am not sure what kind they are, but I have yet to go check them out. I think he said one of them was called something like "Nightrider" or something like that, but Im not sure. I know the guy wouldnt rip me off with bad stuff, but Im not sure what I should do. WEhat kind of power amps are good/cheap?
