DIRECTIONS
• Run a cable from your guitar to
the M234 Analog Chorus’ Input
jack and run another cable from
the M234 Analog Chorus’ Mono
Output jack to your amplier
(for mono operation). To use the
M234 Analog 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.
