This American classic holds the accolade of spawning an entire generation of rock and roll tones. Despite extensive use, this amp proudly sports the ever-classic worn tweed appearance while remaining structurally sound. The replacement Kendrick black frame speakers stand up well against the original P10R Jensens. Internally, it's had a changed power cord, electrolytic caps, and coupling caps, along with some assorted resistors. The speaker wiring was changed as well. A pair of yellow Astrons were salvaged for use in the tone stack, preserving the vintage sound more effectively than one might expect—it sounds excellent. Please refer to the circuit pictures for more details.
