Fender Champ 5C1 preset

Verified · 85/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Fender Champ 5C1 is an early tweed Champ with a 12AY7 preamp tube — a lower-gain device than the 12AX7 that would replace it in later designs. Running 5 watts single-ended through a 6V6GT with a 5Y3 tube rectifier, the 5C1 produces warm, harmonically rich tone that blooms naturally into saturation when pushed. The tweed Champ series is legendarily associated with studio recording: Eric Clapton, Keith Richards, and countless session musicians have tracked guitar parts through Champs.
