I bought this 1965 (month of March) a year and a half ago. My tech made sure both channels were working as they should. The speaker cab, wich came with the amp, is a period correct 212 Bandmaster cab. This is my question/remark. From what I had read, I tought those blackface Bassman would stay clean until a certain point, then begin to break-up. Mine has lots of headroom. It will only begin to break up around 8-9 on the vol knob, and that’s with my 6119 Gretsch! I tried the amp with other cabs:112, 212...and it won’t break up until killing volumes (I knew they were loud). Don’t get me wrong, the sound is superb but I am wondering if I should’t have waited for a piggy back Bandmaster instead???
