Wampler TCD (The Compulsion Drive) overdrive/distortion, captured as 34 NAM A2-Full models at 18 V through a calibrated re-amp rig. Both Mode positions, all four internal DIP-switch combinations, Wampler's own presets and settings from three demo videos. A2-Full ESRs 0.0001–0.0008.
WHAT'S HERE
- TCD-01 to 05: noon baselines. Every knob at noon in Mode down and Mode up with stock switches, then Mode down with the Fat switch right, the Diode switch right, and both.
- TCD-06 to 11: Wampler's suggested settings from the manual: Classic Light Gain, Crisp and Crunchy, Chewy Fat Gain, Tube Killer, Tight Gain and Fuzzy Goodness.
- SW: settings from the Sweetwater demo (Don Carr). TCD-12 to 19 and 51 are stock; TCD-17, 51 and 19 share one EQ at three Gain settings (9:45, 1:15, 3:30). TCD-21 to 26 come from the demo's internal-switch section, with the Diode switch right.
- BW: settings from Brian Wampler's own demo, from minimum Gain (TCD-28) to maximum (TCD-31, 36).
- MN: settings from Michael Nielsen's demo, with the Diode switch right, and the Fat switch right on TCD-48 to 50.
- TCD-45 and TCD-52 use the same knobs and Mode; only the Fat switch differs (left on 45, right on 52). Compare them to hear what Fat does.
Knob positions read from the videos are about ±30 minutes on the dial.
ABOUT THE CONTROLS
Mode toggle: Down = traditional gain stage; Up = cascaded MOSFET stages (more gain and compression).
Internal DIP switches (stock = both left):
- Fat switch right (extra low end).
- Diode switch right (extra diode removed). In the stock (left) position the switch adds an extra clipping diode; moving it right takes that diode out.
NAME KEY
ModeDown / ModeUp = Mode toggle. FatL / FatR, DiodeL / DiodeR = internal switch positions (stock = FatL_DiodeL). DiodeR = extra diode removed.
G / B / M / T = Gain / Bass / Mids / Treble as clock positions on a 12-hour dial (G0300 = 3:00, G1000 = 10:00). Gain runs from 0700 (minimum) to 0500 (maximum).
SW / BW / MN = settings from the Sweetwater (Don Carr), Brian Wampler and Michael Nielsen demo videos. No tag = Wampler's manual presets or the noon baselines.
CALIBRATION AND LEVELS
Input 12.3 dBu, output 22.5 dBu (both at 0 dBFS). Every file keeps the pedal's real output level; nothing was normalised. Level was set to unity (bypass level, -27.2 LUFS on the capture sweep) for every capture, so all 34 sit within 2 dB of each other and of your bypassed signal. Add the trim below to match bypass exactly.
