This is an all original Fender Princeton Reverb w/its 12 watts & original 10″ speaker in excellent condition. It has the exact same circuitry as all Pre-CBS versions prior to the added master volume change in 1974. We plug all guitars for demonstration into these bad ass amps because it makes any & every guitar sound its best. It can make a Harmony Rocket sound like the gods above luv you. This is the smallest amp w/Reverb Leo made & quite delicious in all respects.
