The Brownface era Fender Pro amp carries a robust sonic footprint, equipped with 40 watts of power and a 15" speaker. The legendary harmonic trem does not fail to deliver on this particular amp either - it sounds incredible. Internally, it's had the power cord and electrolytic caps changed, along with a few parts to help service functionality on the bias & tremolo circuit. The screen grid resistors have been changed as well. The trem intensity pot does break connection temporarily when turned all the way down, which causes a slight "pop", but it still functions perfectly. Otherwise, it's practically all original, and features all of the coveted "blue molded" Ajax coupling caps that came with the amp.
