Fender Drip Edge Bassman Head (1968)

Great Bassman sound, plenty of lower frequencies on tap with some lovely throaty break up when pushed.    Someone had tinkered a bit with this circuit so I restored back to the classic blackface AB165 circuit, which was probably how it started out.  Also during servicing we replaced te power tube, installed a bias adjust pot and changed the transformer to one that runs on UK voltage.  Kicks ass.
