ADJUSTABLE OFF DELAY
on
Steve Vai’s
Bad Horsie Wah
The Bad Horsie Wah has a unique switchless
feature. Steve’s personal preference was to have
a slight delay time on the bypass (when you take
your foot off it takes about 1 second for the pedal
to automatically switch to bypass).
After numerous requests for this to be
adjustable, we incorporated an adjustment
located in the pedal. The pedals are still set to
Steve’s specifications at the factory. If you would
like to adjust the off time, follow these steps:
1) Remove four bottom cover screws and bottom
cover.
2) Locate trim-pot labeled “WAH OFF DELAY”
(it is about 3 inches up and about 1-1/2” left from
the center heel end of pedal.
3) Use a miniature screwdriver (like the ones

used for eyeglasses) to turn the center adjustment
of the trim-pot to customize it for your setting.
4) Turning the trim-pot clockwise shortens the
off delay time. Counter-clockwise lengthens the
off delay time. The off delay time can be adjusted MODEL VAI-1
from instantaneous up to 3.5 seconds.
If you have questions about this procedure, feel
free to call 847-639-4646 (ask for Engineering).
