nspired by the vintage Univox Super Fuzz, the TWA WX-01 Wahxidizer captures the iconic, demonic tones of that legendary blue and orange monster while simultaneously reinventing its user interface and control capabilities.

All of the crazy, crunchy, cacophonous octave-fuzz tones of the Univox have been replicated with pinpoint accuracy.

The Fat/Scoop, global EQ switch from the Super Fuzz has been moved to a footswitch, allowing the user to access two completely different fuzz tones on the fly.

For additional tone tweaking, a Parametric EQ circuit has been added to allow for everything from precision fine-tuning to dramatic decomposition of the pedal’s EQ curve.

Better yet, the EQ’s center frequency can be swept three different ways – manually, by playing dynamics or by an external expression pedal. This feature effectively add an envelope-controlled filter to the Fuzz OR turns the pedal into a fuzz/wah/octave, depending on your control method of choice.

Caustic on Guitar, crushing on Bass, the Wahxidizer will turn your tone into a colossal, rusting hulk of expressive, explosive, and corrosive sound.

The control names of the Wahxidizer are taken from the scientific explanation of the oxidation process. Not only will your memory improve by recalling their functions, you will also become smarter by using this pedal!

SUBSTRATE (Level) – Controls output level of effect. Turn CW for more louder.
COMBUSTION (Drive) – Controls the amount of saturation for the Fuzz Effect. Turn clockwise for more dirt/gain/sustain/pain.
ATOM-TRANSFER REAGENT (Frequency) – Adjusts the frequency of the Parametric EQ from low (CCW) to high (CW).
REDOX POTENTIAL HIGH/LOW – Selects between two overall sensitivity settings for the envelope detection circuit to accommodate low and high signal levels.
REDOX POTENTIAL (Threshold) – Adjusts the Threshold setting where the input signal will trigger the envelope detection circuit. Turning CW makes it easier to open the filter.
MEAN BURNING TIME (Speed) – Adjusts the timing for envelope circuit to reach the peak of the filter range. Turn CW for a longer time to reach the filter peak.
ELECTRON TRANSFER REACTION (-/+) – Adjusts the amount of Cut (CCW) or Boost (CW) to the frequency selected by ATOM TRANSFER REAGENT.
ACCELERANT OFF/ON – Turns on envelope-detection circuit
ACCEPTOR/DONOR – Selects between Fat or Scoop Global EQ settings. Fat is full frequency response, while Scoop cuts the midrange.
WAHX ON/OFF – Engages/Disengages the effect.
EXP – Connect external expression pedal or TWA Side Step here to control Frequency of EQ.
LOW/HIGH GAIN – Internal mini switch selects between high or higher gain operation.
