well, the dsl40c is back in the original box and headed back to zzounds. no amount of tube changes or speaker changes made much difference.
also, od1 and od 2 had to be dimed to have any useable sustain. that aint normal. something is wrong with this particular amp and i dont want to get stuck with it.
warmed up the jcm 800 and practiced my set. great tones as always.
fwiw, i've got a tsl 601 and dont like it's tones either.
i figure its just my ears used to hearing a certain sound for half a century
Good move. You like what you like, and that's all that matters. Good luck!
