Fender Pro Tube preset

Verified · 80/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender Pro Tube is a late-1980s channel-switching tube amplifier from Fender's effort to compete in the high-gain, versatile amp market driven by hard rock and metal. Running 60 watts from four 6L6 power tubes, the Pro Tube offers a clean American channel alongside a gain-enhanced lead channel designed for sustain and crunch. The Pro Tube series represents Fender's transition toward modern multi-channel designs without abandoning the 6L6 tube platform central to the brand's identity. It is less celebrated than the classic Fender designs but captures a specific moment in the company's commercial evolution.
