The Fender Princeton Reverb is a guitar amplifier combo, essentially a Princeton with built-in reverb and vibrato.

The 12-Watt Blackface version was introduced in 1964 and available until 1967, in 1968 it was replaced by the Silverface version with a drip edge around the grill cloth (added and removed in 1969) and a change in circuitry. The rectifier was changed from a 5ar4 to a 5u4gb during the Silverface years along with a change in bias resistor value, a "boost" pull switch to the volume control pot was added in 1977. In 1980 and 1981 the Silverface version was cosmetically changed back to the Blackface. It was discontinued in 1981.

The reason these Princeton Reverbs are so widely desired is their great tone and versatility. These amps have that great clean tone that the blackface era amps are known to have. Add a little reverb and it’s clean tone heaven. But, you’ve got to crank the amp up just a little to the sweet spot between clean and crunch to deliver the goods. The driven tone is smooth but gutsy enough to please any rock and roller. These amps are perfect for any guitar heavy style of music from blues to rock to country and everything in between. Their size allows them to be comfortable at home, in the studio or at a show with a microphone out front.
