Fender Princeton Recording Amp preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Princeton Recording Amp is a 2006 Fender combo built on a blackface Princeton Reverb-style valve circuit. Three 12AX7WAs and a 12AT7 reverb driver run Volume, Treble, Bass and spring reverb into two fixed-bias 6V6GTs, rated 15 watts into an internal 8-ohm load. That output feeds a transimpedance attenuator and a solid-state power amp, with solid-state overdrive and compressor effects, an effects loop, line out and headphones.

• Wattage: 20W
• Channels: 1
• Preamp tubes: 3× 12AX7WA, 1× 12AT7
• Power tubes: 2× 6V6GT

Tags: hybrid, reverb, 6v6, clean, low-wattage.

Schematic-derived preset files for the Neural DSP Quad Cortex and 16 Fractal and Line 6 modelers: Axe-Fx II/XL/XL+, Axe-Fx III, FM3, FM9, and the full Helix family (Floor, LT, Rack, HX Stomp, HX Stomp XL, Native).

Gridleak extracts amp parameters from original circuit schematics using AI vision — component values, gain staging, tone stack topology, tube types — then generates native preset files for every supported modeler. Every extraction is scored 0–100 and the score is published.
