The PLATE setting provides a shimmering smooth wash of space that’s a go-to choice from the studio recording world. SPRING sets a new standard for truly authentic sounding reverb without coiled metal-a perfect recreation of the classic amp-based effect, with the Tone control taking you from dark vintage amp spring, through classic jangle, to bright surfy splatter. EPIC is a unique combination of multiple interwoven analog-tone delay lines and complex modulation-perfect for solos from that more shaded part of the lunar landscape. MOD throws down a plate-flavored spaciousness with richly organic modulation in the feedback path. The ROOM style adds subtle body and projection to your guitar tone at shorter decay times while longer decay times yield rich organic space that doesn’t wash out. PAD closes out the line-up with a unique combination of sub-octave + octave-up with echoes + shimmer + synth/organ modulation + reverb.
Connect a Dunlop DVP series volume/expression pedal to the expression jack to toggle and blend between two different knob setting configurations. The Reverb includes 100% wet mode, stereo input and output capability, and true relay or trails bypass.
• Six meticulously crafted reverbs in one pedal
• Audiophile quality analog and digital audio paths
• Dry path is 100% analog
• Studio-grade low noise oor
• Trails Bypass mode lets e ect
ring out after turning the pedal o
• Expression pedal jack for foot control of all knob settings
• Stereo In/Out capability when using TRS cables
The MXR Reverb requires 9 volts (240mA) and can be powered
by the included Dunlop ECB003/ECB003EU adapter
• 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 ampli er. 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 e ect 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.
• 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.
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.
• 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 re ection slap-back sound. Indicated by green LED.
• PAD: Blend of octave down
and octave up synth sounds with reverb e ect. 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.
USING AN EXPRESSION PEDAL
An expression pedal such as the DVP4 Volume (XL)TM Mini Pedal or the DVP3 Volume (X)TM Pedal can be used to toggle and sweep between two di erent setting con gurations:
• Connect an expression pedal to M300’s EXP jack using a TRS cable, and set 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 di erent setting con guration.
• Moving rocker back and forth will move e ect sound smoothly between those two settings.
The M300 can be run in either Mono (default) 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 ampli er. Next, set internal STEREO/MONO switch to its LEFT position (see Diagram A). Note: When M300 is bypassed, output ring connection will only receive
signal if M300 is set to Trails Bypass mode (see below).
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 o . Re-enter Startup Mode and follow relevant steps to change settings again.
1. Disconnect M300 from power supply and set DECAY and MIX controls to 12 o’clock.
2. Enter Startup Mode by pushing down and holding TONE knob while connecting M300 to its power source.
TRAILS BYPASS MODE
The M300 uses a “true bypass” relay by default, shutting o e ect and hardwire bypassing the tip connection signal as soon as you turn the pedal o (ring connec- tion uses bu ered bypass). The M300 can also be operated using Trails Bypass mode, which uses
a bu ered bypass and allows the reverb e ect to ring out even after you turn the pedal o .
1. After entering Startup Mode, release TONE knob. LED column will now re ect bypass mode
status. Green LEDs indicate factory-set True Relay Bypass mode, while red LEDs indicate Trails Bypass mode.
2. Press TONE knob to toggle between modes.
3. Depress footswitch to exit Startup Mode and resume normal operation.
The M300 can be set so that only the wet signal is sent to your ampli er.
1. After entering Startup Mode, observe LED column for mode status. Green LEDs indicate factory-set Dry mode. Red LEDs indicate Wet mode.
2. While still pushing down on TONE knob, rotate DECAY or MIX knob clockwise past 12 o’clock to select Wet mode, indicated by red LEDs. To return to Dry mode, rotate DECAY or MIX knob counterclockwise past 12 o’clock. Green LEDs will light up and red LEDs will turn o .
3. Release TONE knob to save your selection and depress footswitch to exit Startup Mode and resume normal operation.
