In 1980 and 1981 the silverface version was cosmetically changed back to the Blackface. It was discontinued in 1981.

Fender Princeton Reverb II

This Paul Rivera-specified Fender guitar amplifier, introduced in 1982, a completely different and significantly more powerful amplifier, replaced the Princeton Reverb. Designed by Ed Jahns, it featured a built-in reverb, treble boost and mid boost controls, and a switchable lead (overdrive) effect. The Princeton Reverb II was removed from the Fender pricelist in 1986.
