MXR Joshua Ambient Echo Pedal

Inspired by a certain Irish guitarist's delay sound, the MXR M309 Joshua produces delay tones so lush, you can get lost in its mysterious ways.

The MXR Joshua Ambient Echo is a one-stop-shop sunk deep into iconic soundscapes, from tonal trips out of the '60s and '70s to the ethereal ambience of the '80s soundscapes. Once upon a time, you needed a whole rack processor get these tones, but this pedal comes with everything you need to cop that distinct tonal palette in a modern and user-friendly format -- and it's already dialed in and ready to go.

EXTERNAL CONTROLS:
ECHO 2: button adds secondary repeats at note tempo (indicated by blue LED)
TRAILS: button toggles effect Trails mode on/off (red LED indicates on)
DELAY: knob adjusts length between repeats
MOD: knob adjusts intensity of modulation
VOICE: knob adjusts mix of -1, +1, and +2 octave signal blend
REGEN: knob sets number of repeats
DIVISION: knob selects tempo of primary repeats
MIX knob: adjusts overall volume of effect signal
CTR: jack allows an expression pedal to control settings or tap switch to set tempo around tempo selected by DIVISION knob
FOOTSWITCH: toggles effect on/bypass (blue LED indicates on) and engages Tap mode

POWER:
The MXR Joshua Ambient Echo requires 9 volts (300mA) and can be powered by the Dunlop ECB003 9-volt adapter or the MXR Iso-Brick and Mini Iso-Brick power supplies. This pedal cannot be powered by a battery.

DIRECTIONS:
1. Run a cable from your guitar to the M309's IN jack and run another cable from the M309's OUT jack to your amplifier.
2. Start with all knobs except VOICE and DIVISION at 12 o'clock. Set VOICE and DIVISION knobs read more fully counterclockwise. Turn the effect on by depressing the footswitch.
3. Rotate DELAY knob clockwise to increase the time between repeats or counterclockwise to decrease it.
4. Rotate MOD knob clockwise to increase the intensity of the modulation effect or counterclockwise to decrease it.
5. Rotate VOICE knob clockwise to mix in a blend of -1, +1, and +2 octave signals.
6. Rotate REGEN knob clockwise to increase number of repeats or counterclockwise to decrease it.
7. Rotate DIVISION knob clockwise to cycle through rhythm settings: note, dotted note, note, note triplet, double delay with an 1/8 note, and dotted 1/8 note.
8. Rotate MIX knob clockwise to increase overall volume of effect signal or counterclockwise to decrease it.
9. To engage a second repeat set to a 1/4 note, push the ECHO 2 button. To change the tempo the second repeat, press and hold the ECHO 2 button and turn the DIVISION knob to select your new preference. It will stay in this mode until you change it back the same way.
10. Push the TRAILS button to allow your repeats to gradually fade out according to your REGEN setting rather than stop abruptly when disengaging the pedal. This button will illuminate red when Trails mode is engaged.

FOOTSWITCH: BYPASS & TAP TEMPO:
1. By default, the FOOTSWITCH toggles the pedal on or off in a true bypass system. When Trails Mode is engaged, buffered bypassing is used.
2. The FOOTSWITCH can also be used as a tap tempo switch to set the rhythm of your primary repeats. Press and hold for 1 second to engage tap tempo mode, and then tap your desired rhythm.

USE AN EXPRESSION PEDAL TO BLEND BETWEEN TWO SETTING CONFIGURATIONS:
An expression pedal such as the such as the DVP5 Volume (X)8 Pedal can be used to toggle and sweep between two different setting configurations. First, set the CTR switch to its TAP/EXP (left) position. Next, run a TRS cable from the expression pedal to the M309's CTR jack. Set rocker to its heel-down position. Adjust knobs and set mode buttons desired. Move rocker to its toe-down position. Adjust knobs and mode buttons as desired to a different setting configuration. Moving the rocker back and forth will transition smoothly between the sounds created by the two settings.

USE AN OFF-BOARD TAP SWITCH TO CONTROL TEMPO:
An off-board tap switch such as the M231 MXR TRS Tap Switch can be used to control the delay time based on the rhythmic value chosen with the DIVISION knob. First, set the CTR switch to its TAP/EXP (left) position. Next, run a standard mono patch cable from the tap switch's output jack to the M309's CTR jack. While the M309 is on, tap your desired rhythm onto the Tap Tempo Switch.

FREEZE MODE:
While using an off-board tap switch as described above, holding down the off-board switch will freeze the delay lines at max feedback and prevent any new signal from engaging with the delay until the switch is released.

STEREO OUTPUT:
To operate in stereo mode, run a TRS splitter cable from the M309's OUTPUT jack to your chosen inputs. Press and hold the ECHO 2 button, and rotate the VOICE knob fully clockwise to select stereo output mode. ECHO 2 and TRAILS buttons will flash to confirm. To change back to mono output mode, follow the same steps, and rotate the VOICE knob counterclockwise.

The CTR jack can also be used as a right channel audio output. Set the CTR switch to its right position, and run an instrument cable from the M309's CTR jack to a separate output source. The ring connection on the OUT jack will be muted.

ADVANCED SETTINGS:
By pressing and holding the ECHO 2 or TRAILS buttons while adjusting any of the pedal's knobs, you can fine-tune various functions. Dunlop recommends leaving these settings as they are unless you understand how they work at a deep level as any changes can alter the overall sound of the pedal.

- Echo 2:
- Delay (HARD OR SOFT FLASHING): Rotate counterclockwise for soft-flashing ECHO 2 and bypass LEDs or clockwise for hard-flashing LEDs.
- Mod (SYMMETRICAL REGENERATION): By default, this pedal employs symmetrical regeneration to ensure that dual delay signals set to different rates fade out at the same time. To disable this feature, rotate the knob counterclockwise. TRAILS LED will flash to confirm.
- Voice (STEREO MODE): Rotate clockwise to engage stereo mode or counterclockwise to disengage it. ECHO 2 and TRAILS LEDS will flash to confirm.
- Regen (ECHO 2 REPEATS): Rotate clockwise to increase the number of secondary delay signal's repeats in relation to the primary delay signal's regeneration or counterclockwise to decrease it.
- Tap (ECHO 2 TAP DIVISION): Rotate to select tap division of secondary delay signal.
- Mix (ECHO MIX): Rotate clockwise to increase the mix of the secondary delay signal relative to the first or counterclockwise to decrease it.

-Trails:
- Delay (TRAILS MODE FLASHING): Rotate clockwise to make TRAILS LED flash at reference clock rate or counterclockwise for a solid LED.
- Mod (MODULATION RATE): By default, the MOD knob controls both the depth and rate of the modulation effect. Rotate this knob to turn it into a depth control when TRAILS button is held down and a rate control when TRAILS button is released.
- Voice (HIGH CUT FILTER): Rotate clockwise to reduce high-end frequency range, from 12kHz fully counterclockwise to 2kHz at noon to 200Hz fully clockwise.
- Regen (REVERB DECAY): Rotate clockwise to increase reverb decay or counterclockwise to decrease it. Making this adjustment will disconnect this setting from control by the Delay knob.
- Tap (COMPRESSION THRESHOLD): Rotate clockwise to raise compression threshold or counterclockwise to lower it. Midpoint is the default setting.
- Mix (REVERB MIX): Rotate clockwise to increase the mix of reverb or counterclockwise to decrease it.

Return to Factory Settings:
To return all parameters to their factory settings, simply press and hold ECHO 2 and TRAILS buttons for five seconds the main LED will flash to confirm.

I purchased the MXR Joshua right here at zZounds.com. I have been playing guitar over 30 years. I am a professional amateur guitar player. I love U2. I was so excited about this pedal. When I received it I noticed there was no manual and I thought I could wing it on the settings. Nope. I couldn’t find a sound I liked. The voice which sounds essentially like an organ was too overwhelming. The Mod was way too wobblie. It was terrible. I finally decided to return it. Then I realized I didn’t read the manual. I knew there had to be more to this pedal. I love U2. I figured it would sound like the Edge with all knobs at noon. Not the case for me. I downloaded the manual from MXR. I then learned the Advanced Settings. Then I really saw what this pedal can do. Adjusting the Hi cut helps the Voice octave sound helped blend it more and adjusting the modulation depth by holding down Echo 2 and adjusting the Mod knob counterclockwise for less depth or clockwise for more. Then I discovered the dip switch on the side to change the 2nd input jack to allow a second amp. Then you need to put it in Stereo mode and that’s where this pedal really shines. Having the stereo output. I think you’re going to love this pedal and it’s very diverse in what you can do. Learn the Advanced Settings before you receive it so you’re ready. I absolutely love this pedal now that I know how to use it. It drives my creativity and sometimes I will break out into the Edge sound. This pedal is a hit. I would read more recommend it for sure.
