Dunlop WA38 User manual

  • Hello! I've reviewed the user manual for the MXR Wylde Audio WA38 Chorus pedal and am ready to assist you. This manual details the pedal's controls, including depth, rate, level, and tone shaping, as well as how to use its stereo mode. If you have questions about its operation or features, please ask!
  • What does the THRU OUTPUT jack do?
    What is the purpose of the LOW and HIGH knobs?
    How can I control the speed of the chorus effect?
Wylde Audio Chorus
Celebrate the 20th anniversary of the explosive
collaboration between Dunlop and Zakk Wylde with
the MXR Wylde Audio Chorus. This pedal is Zakk’s
secret weapon for thickening up walls of distortion
and adding liquid dimension and texture to clean
passages.

Basic Operation
1. Run a cable from your guitar to the WA38’s INPUT jack
and run another cable from the WA38’s OUTPUT jack to
your amplier. Optional Stereo Mode: run an additional cable
from the THRU OUTPUT jack to the input of a second amp.
Using this jack automatically sends the delayed signal only
to the MONO output jack when the eect is on and outputs
a buered copy of the input signal.
2. Start with all knobs at 12 o’clock. Turn the eect on by
depressing the footswitch.
3. Rotate the DEPTH knob clockwise to increase the intensity
of the eect or counterclockwise to decrease it.
4. Rotate the RATE knob clockwise to increase the speed of
the chorus eect or counterclockwise to decrease it.
5. Rotate the LEVEL knob clockwise to increase overall eect
volume or counterclockwise to decrease it.
6. Rotate the LOW knob clockwise to retain more low end or
counterclockwise to cut more low end.
7. Rotate the HIGH knob clockwise to retain more high end or
counterclockwise to cut more low end.
The MXR® Wylde Audio Chorus is powered by a single
9-volt battery (remove bottom plate to install), a 9-volt AC
adapter such as the Dunlop ECB003, or an MXR® Brick™
Series power supply.
