Checkout this highly sought after 1964 Blackface Fender Princeton Amp ("non-Reverb"). A great amp for recording and small gigs. With built-in tremolo/vibrato circuit and 12 watts pushing a 10" Oxford speaker; in between the smaller Vibro Champ and the bigger Deluxe Amp, the earliest Blackface Princetons have a couple anomalies -- the "tuxedo" cosmetics from using leftover Brownface parts and a simpler Tone circuit. By the fall of '64, the more common Blackface-era cosmetics (numbers on the knobs, not the faceplate) came about and the circuit was revised to have separate controls for Bass and Treble.
