Basic Operation
1. Run a cable from your guitar to the M306's INPUT jack
and run another cable from the M306's OUTPUT jack to
your amplifier.
2. Start with all controls at 12 o'clock.
3. Turn the effect on by depressing the footswitch.
4. Rotate DRY knob clockwise to increase output level of
dry signal or counterclockwise to decrease it.
5. Rotate SUB-1 knob clockwise to increase output level
of SUB-1 signal or counterclockwise to decrease it.
6. Rotate SUB-2 clockwise to increase output level of
SUB-2 signal or counterclockwise to decrease it.
7. Rotate OCT+1 knob clockwise to increase output level
of OCT+1 signal or counterclockwise to decrease it.
8. Rotate OCT+2 knob clockwise to increase intensity of
overdrive or counterclockwise to decrease it.
9. Rotate the MOD knob clockwise to increase rate
of modulation or counterclockwise to decrease it. To
remove modulation from signal, rotate the MOD knob
fully counterclockwise. The sound of the modulation is
dependent on the pitch-shifting setting as determined by
the MONO switch: in the default polyphonic mode, the
modulation circuit simulates the Leslie speaker effect,
while in monophonic mode, it sounds similar to the MXR
Phase 90.
10. Push the FUZZ switch to add fuzz to all five signals.
Blue LED indicates fuzz is active. To adjust the volume
level of the fuzz effect, press and hold the FUZZ switch
until the blue LED flashes. Use the DRY knob to set your
desired fuzz volume, and then push the FUZZ switch
again to save the setting.
11. Push the MONO switch to toggle toggle from
polyphonic pitch shifting—which can be applied to
single notes as well as full chords—to monophonic pitch
shifting, which focuses on a single note at a time. When
in monophonic mode, the OCT+1 and OCT+2 signals will
resemble the sound of an Octavio Fuzz with the intensity
dialed all the way back. Red LED indicates monophonic
mode is active.
