Though intended for practice situations, the Princeton was capable of big tube tone, and Fender's world-class Reverb and Vibrato effects were the icing on the cake. From its inception `til today, countless guitarists have chosen it as their go-to studio amp, crafting signature sounds with a stomp box or two feeding a simple miked-up Princeton. Today, original Princeton Reverb amps are prized collectibles, and becoming harder to find. The new '65 Princeton® Reverb Amp offers today's players all of the great tone and dynamics of the original. The robust 15-Watt platform is a wise choice for creating tube tone in a small space, and even provides enough output for small gigs and rehearsals. 1965 Princeton® Reverb circuit with all tube circuitry Two Groove Tubes® 6V6 output tubes Three 12AX7 preamp tubes One 12AT7 tube 5AR4 rectifier tube 15 Watts output power 10" Jensen C-10R speaker for spanky vintage tones Genuine Fender tube-driven spring Reverb by Accutronics® Genuine Fender tube tremolo ("Vibrato") Genuine Fender Blackface cosmetic treatment Vintage Reverb/Vibrato footswitch Fitted cover included 5 year warranty (US and Canada, other territories may vary) The World's Most Popular Instrument Amplifiers.
