I am thinking of buying a solid state bass amp head. I currently use an Orange Terror 500w for my 1973 EB3 bass when I am playing the music of FREE, and it sounds great, but my Ernie Ball Musicman Sterling bass, which I use for Bad Company, doesn't sound so good through the same amp. I think it needs solid state, whereas the Terror has a valve pre-amp. Can anyone suggest an amp head that I can get 500w from using my two cabs? Orange 400w and a Bareface 600w. Both are 8ohms.
