e/Fender Vibrasonic

Information
has gloss	eng: The Fender Vibrasonic was an amplifier made by Fender. It was introduced in 1959 and was discontinued in 1964. At the time of its introduction, the Vibrasonic-Amp was the first amplifier design to displace the Fender Twin as the company's new top of the line or "flagship" model. This elevated status was short-lived however, as the 6G8, hi-powered blonde Twin-Amp reappeared in mid 1960.The Vibrasonic was debuted as one of the six Professional Series of Fender Amplifiers. These are the first six models to make the transition to the new tolex-covered, forward facing control plate design that would gradually replace the tweed-covered cabinet design so prevalent during the 1950s. Outside of a few small variations like the transformers, speaker array and negative feedback resistor, these 6 amplifiers shared nearly identical circuits.
