MC406 BUFFER

DESCRIPTION

• Low noise buffer in a small,
rugged steel housing

• Hi and Lo cut options with
indication LEDs

• Adjustable 0 to +6dB gain slider

• Features a pass-through 9-volt
jack for other effects

DIRECTIONS

• Run a cable from your guitar to
the Buffer’s Input jack and run
another cable from the Buffer’s
OUTPUT 2 jack to the next pedal
in your effects chain.

• Optional: Run a cable from
OUTPUT 1 to tuner, separate
effects chain, or second
amp to receive unbuffered
INPUT signal.

• Move GAIN slider to the right
to compensate for signal loss
or add gain.

• To reduce excessive high end
broadband noise, press the HI
CUT switch.

• To reduce excessive low end
feedback noise, press the LO
CUT switch.

• To access (INTERNAL) switch,
remove INPUT and OUTPUT
jacks with wrench or nutdriver
and slide inner casing
from housing.

POWER

The MC406 BUFFER can be
powered by a Dunlop ECB003
AC adapter (ECB003E in Europe),
a Dunlop DCB10 DC Brick power
supply, or other well regulated
9 volt DC supply with a minimum
of 50 mA current capability, and
a 5.5 X 2.1 mm positive barrel
connector.
