I built a 5E3 head a couple months back. Built a 2x 10 cabinet for it with Weber 10F125 speakers. I wanted an amp for rehearsals and small shows when that’s possible again. Sounded great. Just finished a 12 inch cabinet with a Weber 12A125A in it. This sounds almost too good! Is it the 1x12, alnico vs ceramic, poplar vs pine or just the circuit as meant to be?
