Comments: Tremolo: 5G13: 2 x 7025 (harmonic vibrato) 6G13-A: 12AX7, 12AX7 and 7025 (harmonic vibrato) Mode 6G13-A’s tremolo circuit left 12AX7 unused. Some early Vibrasonics have a plugged hole in the rear panel labeled “pulse adj.” located about 1½” to the right of speaker jack. As the label implies this may have been a control to adjust the waveform of the tremelo. 60 Vibrasonic Rear Panel

    What’s the difference between the brown vibrio sonic and brown pro?

    Hi Mark,
    The main difference is that the Vibrasonic wanted to have lots of clean headroom,so the heavy duty transformers from the 80watt showman were used,which could easily handle the 40 watts without overheating…think of it as a showman with two 6L6’s removed….and also it was fitted with a JBL instead of the Jensen speaker.The Vibrasonic also had an extra valve for the Long tail phase inverter Tremolo system which was the most complicated system Fender had developed,giving a very distinctive sound!
    The Vibrasonic 1 x 15″ Combo cost more than a Showman.

    ps the VibrOsonic was a silverface master volume twin reverb fitted with a 15″ speaker for Pedal Steel….not to be confused with the VibrAsonic…

    Has anyone here ever seen a blackface 1963 vibrasonic?

      Someone certainly could have retolexed a ’63 in black at some point but the “Blackface” era didn’t start until ’64.
