While Fender's 'Brownface' Era amplifier lineup is chock full of legendary circuits (the Deluxe and Princeton come to mind), the mid-powered Super is an extraordinary standout that combines portability and power with the hypnotic and lush Harmonic Vibrato circuit.
At 40 watts output, the 2x10 Super is one of the more capable tube combos of its decade. With a refined power section and the addition of harmonic vibrato, the Super showcases Fender's departure of the more raw Tweed sound for something more robust and focused. Low end response is tighter, and the upper midrange is well defined, giving this amp great punch with some nice cut that works very well in a band context.
The addition of the Harmonic Vibrato circuit is what made these amps so special; a unique effect that alternates between high and low frequencies, creating a swirly "Uni-vibe" type of effect. Harmonic Vibrato was easily the most complex vibrato circuit ever produced by Fender, and only found its way into certain 'Brownface' and 'Blonde' era amplifiers of the early 1960s.
This is an exceptionally clean and excellent sounding example, featuring its original Oxford gold frame 10K5 speakers. It has recently been serviced by David Allen of Allen Amplification (noted boutique amplifier builder known for his 'Brownface' style builds) including replacement of the original output transformer. The power transformer is original. The original 6G4-A Tube Chart shows a date stamp of 'LH' which denotes the amplifier was completed in August of 1962. It comes with an aftermarket vintage style canvas cover.
