With the exception of a 68 Princeton Reverb with all RCA tubes, modded for 18-20 watts and a 12 inch Weber, which produces some of the most beautiful tones BTW, Ive stayed in the 40-50 watt area but changed to amps that get good OD tones at lower volumes. Switching from a Hot Rod Deluxe to a Traynor YCV40 started me on that path, and of course purchasing my first Hamer (96 Artist Custom) about a year ago didn't hurt any...
