This look of this amp presents a classic "American workhorse" look to it, like a beat up pair of Levi 501's, or anything else that was built to last. As is often the case, there's an equal correlation from the look on over into the sound, and this amp is no different - it sounds fabulous! Internally, it has a changed power cord, new filter caps, and the coupling caps have been changed with a mix of older/newer orange drops. All of the original resistors still remain. Thankfully all of the transformers are still original, and the speaker was changed to a Celestion Alnico Blue. This perfect recipe of features results in a formidable sounding player grade piece!
