AUTOWAH
When you select Autowah from the Wah Mode switch, you get the classic envelope-based effect.
But, rather than using a generic bandpass filter, it utilizes the vintage Clyde McCoy voicing.
Unlike typical autowah pedals, Wahzoo literally turns into an automatic, dynamically controlled
vintage wah!
Autowah Sensitivity
Since the filter is triggered by how hard or soft you hit the strings, and the general output of
your guitar’s pickups, it’s important to find the “sweet spot” on the Autowah Sens knob. If you
use single-coil pickups, you can move the control clockwise until you find a spot that delivers
the “quack” you’re looking for. As you move the knob counter-clockwise, you can play harder
and/or use higher-output humbucker pickups before triggering the filter.
Normal and Reverse Envelope
With the treadle in the “heel back” position, the autowah filter is normally closed. The amount
the filter opens, and the time before it closes is dependent on how hard you hit the strings. In this
setting, it’s possible to re-create classic wah sounds like “Voodoo Child (slight return)” all based
on your dynamics!
In the “toe forward” position, the autowah filter is now in “reverse” and normally open. Now, you
start with a full-up wah sound, and the filter closes by playing harder. You can also experiment
with changing the envelope on the treadle as you play.
TIP: Try doing your chord rhythms in the “heel back” position and your single-note lines in “toe
forward” position. You can also achieve an almost rhythmic envelope effect by rocking the treadle
back and forth in tempo.
STEPWAH
™
When you select Stepwah, Wahzoo will automatically jump through different wah treadle positions
as a rhythmic pattern. You can store up to 4 custom sequences of your own creation. Just like
Vintage and Autowah, Stepwah also utilizes the classic Clyde McCoy wah sound.
Wahzoo includes 4 preset patterns for Stepwah. Use the Step Sequence knob to select the sequence
you want. Once you get a feel for it, replace the presets with your own patterns. Experiment and
enjoy, this is really fun! Don’t worry, you can always restore the original presets if you want.
