Basic Operation

Power Directions

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.

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.
