This 1961 Pro has a funky, vintage look with a great sound to match. The original covering has been replaced and has since aged in the sunlight. The original baffle has also been swapped for a modern one, which is solid and sturdy in contrast. The original Jensen C15N has held up well and sounds fantastic.
Internally, the power cord, electrolytic caps, and screen grid resistors have been replaced. A few of the original "Blue Molded" Ajax coupling caps have been swapped out, but about half still remain, along with most of the original resistors. Thankfully, these updates have resulted in a tremendous-sounding harmonic tremolo, one of the highlights of the Brown era Fender amps. Please refer to the circuit pictures for details, along with the specs section for transformer information.
