POWER
The MXR ZW38 Black Label Chorus

battery (accesed by removing
the bottom plate of the pedal),
a Dunlop ECB003 AC adapter
(ECB003E in Europe) or a Dunlop
DCB10 DC Brick power supply.
DIRECTIONS
• Run a cable from your guitar to
the Black Label Chorus’ Input
jack and run another cable from
the Black Label Chorus’ Mono
Output jack to your amplifier
(for mono operation). To use the
Black Label Chorus in 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 effect is on
and outputs a buffered copy of
the input signal.
• Start off with all of the controls
set to 12 o’clock.
• Turn the effect on by depressing
the footswitch. The illuminated
blue LED indicates the unit is on.
• Rotate the Depth control
clockwise to increase the
intensity of the effect.
• Rotate the Rate control clockwise
to increase the speed of the
chorus effect.
• Adjust the Level control to set the
overall volume of the effect.
• Adjust the Low and High controls
to set desired tonality of the
chorus effect.
