My Ceriatone 2555 / Voodoo modified w/ F&T filter caps, SED =C= EL34s and Mercury Magnetics Tranformers is just the Marshall tone I have grown to LOVE. If I didn't have that and be SO in love with it and such, then the PT100 wouldn't be going anywhere. That 2555 tone is so unique...and even better with what Trace did to it...I just haven't had anything top it yet.
