DESCRIPTION
• Six meticulously crafted reverbs
in one pedal
• Audiophile quality analog and
digital audio paths
• Dry path is 100% analog
• Studio-grade low noise oor
• Relay true bypass and delay
trails modes
• Expression pedal jack for foot
control of all knob settings
• Stereo In/Out capability when
using TRS cables
DIRECTIONS
• Run a standard instrument cable
from your guitar to the M300’s
INPUT jack and another cable
from the M300’s OUTPUT jack to
your amplier. If using an expres-
sion pedal, run a TRS cable from
the M300’s EXP jack to your
expression pedal.
• Start with all controls at
12 o’clock.
• Turn the effect on by depressing
the footswitch.
• Push in the TONE control to
cycle through reverb styles,
indicated by red or green LEDs
in the LED column. See REVERB
STYLES section for a description
of each style.
REVERB STYLES
• PLATE: Classic studio plate
reverb. Indicated by green LED.
• SPRING: Classic guitar amp
reverb. Indicated by red LED.
• EPIC: Multiple interconnected
modulated delays. Indicated by
green LED.
• MOD: Modulated studio plate
reverb. Indicated by red LED.
• ROOM: Simulates small room,
early reection slap-back sound.
Indicated by green LED.
• PAD: Blend of octave down and
octave up synth sounds with
reverb effect. Indicated by red
LED. Use TONE control to
blend—fully counterclockwise
provides one octave down and
fully clockwise provides one
octave up. The 12 o’clock
position provides both an octave
up and an octave down. Use
DECAY control to set synth pad
and reverb decay.
• Rotate DECAY control clock-
wise to increase length of reverb
decay or counterclockwise to
decrease it.
• Rotate TONE control clockwise
for a brighter reverb sound or
counterclockwise for a warmer
reverb sound.
• Rotate the MIX control clockwise
to increase reverb signal level
or counterclockwise to decrease
it. Fully clockwise results in an
equal 50/50 mix of reverb and
dry signals.
POWER
The MXR Reverb requires 9 volts
(240mA) and can be powered by
the included Dunlop ECB003/
ECB003E adapter or the Iso-Brick
™
Power Supply. Cannot be powered
by a battery.

USING AN EXPRESSION PEDAL
An expression pedal such as the
DVP4 Volume (XL)
™
Mini Pedal or
the DVP3 Volume (X)
™
Pedal can be
used to toggle and sweep between
two different setting congurations:
• Connect an expression pedal to
the M300’s EXP jack using a TRS
cable, and set the rocker to its
heel-down position. Adjust
knobs as desired. Note:
Expression pedal cannot be
used to change reverb style.
• Move rocker to its toe-down
position. Adjust knobs
as desired to a different
setting conguration.
• Rocking the pedal back and
forth will move your reverb
sound smoothly between
those two settings.
MONO/STEREO INPUT
The M300 can be run in
either Mono or Stereo modes,
selectable via internal switch,
which determines tip/ring input
connection. For a stereo setup,
run a TRS splitter cable to the
M300’s INPUT jack and another
from the M300’s OUTPUT jack to
your amplier. Next, set internal
MONO/STEREO switch to its
LEFT position (see Diagram A).
ADVANCED FUNCTIONS –
STARTUP MODE
Additional functions can be
accessed by entering Startup
Mode. Advanced function settings
will remain in selected state, even
after pedal is powered off. Simply
re-enter Startup Mode and follow
the relevant steps to change the
settings again.
1. Disconnect the M300 from
power supply and set DECAY
and MIX controls to 12 o’clock.
2. Enter Startup Mode by pushing
down and holding the TONE
knob while connecting the
M300 to its power source.
TRAILS BYPASS MODE
The M300 normally operates
using a “true bypass” relay, which
shuts off the effect and hardwire
bypasses the signal as soon as you
turn the pedal off. Alternatively, the
M300 can be operated using Trails
Bypass, which allows the reverb
effect to ring out even after you
turn the pedal off.
1. After entering Startup Mode,
release TONE knob. LED will
now reect bypass mode status.
Green indicates factory-set True
Relay Bypass mode, while red
indicates Trails Bypass mode.

MONOSTEREO
2. Press TONE knob to toggle
between modes.
3. Depress footswitch to exit
Startup Mode and resume
normal operation.
WET MODE
The M300 can be set so that
only the wet signal is sent to
your amplier.
4. After entering Startup Mode,
observe LED for mode status.
Green LED indicates factory-set
Dry mode. Red LED indicates
Wet mode.
5. While still pushing down on
TONE knob, rotate DECAY or
MIX knob clockwise past 12
o’clock to select Wet mode,
indicated by red LED. To return
to Dry mode, rotate DECAY or
MIX knob counterclockwise past
12 o’clock. Green LED will light
up and red LED will turn off.
6. Release TONE knob to save your
selection and depress footswitch
to exit Startup Mode and resume
normal operation.
NOTE :
You may notice that the M300’s
housing warms up while on. This is
completely normal. Take care when
operating in extremely high ambient
temperatures or direct sunlight.
