This is a fantastic sounding old Fender that does the trick all the times. No humms, no squeeks. Great working condition and cosmetics 8/10.
The Pro (originally called the Professional) is one of Fender's oldest amp designs. Like other Fender amps, the Pro evolved in the '50s and '60s with different cabinet styles. In the mid-'60s the Pro was replaced by the Pro Reverb, and the design was changed to the Silverface style in 1973.
