Congratulations on your purchase of the Grand Canyon, a superior sounding,
massively powerful Delay and Looper pedal. Within the Grand Canyon are a vast
array of awe-inspiring effects. Explore a wide range of delays and textures,
including pristine or bitcrushed digital, exquisite Deluxe Memory Man, rhythmic
drum, warm tape, plate reverb, polyphonic pitch shift, and ethereal shimmer. The
Grand Canyon even has a full-featured looper which can be used simultaneously
with any of the delay effects to conjure lush, layered soundscapes. Fine tune the
effects with a broad array of intuitive controls, and you're in for a truly inspiring
and grand experience.
WARNING: Your Grand Canyon comes equipped with an Electro-Harmonix 9.6DC-200BI
power supply. The Grand Canyon requires 150mA at 9VDC with a center negative plug.
Use of the wrong adapter or a plug with the wrong polarity may damage your Grand
Canyon and void the warranty. Do not exceed 10.5VDC on the power plug. Power supplies
rated for less than 150mA will cause the Grand Canyon to act unreliably.

    SHIM A mixture of octaves and modulated delay plus compression creates shimmering cascaded soundscapes. SAMPLE/ Play a note or strike a chord; the Grand Canyon repeats HOLD the echoes indefinitely until your next note or chord. DRUM Faithful emulation of a magnetic drum echo with a host of playback head configurations for creating musical rhythmic echo patterns.

    3. For stereo operation, connect R OUT to another amp. DIALING IN A STANDARD DIGITAL DELAY EFFECT 1. Ensure none of the buttons at the top left of the Grand Canyon, like TAILS, are lit. If any button is lit, press the button once to disable it.
  • Page 5 CREATING A LOOP 1. To create a loop, the LOOPER LED in the center of the Grand Canyon must be lit. 2. To cycle through the three modes – Delay, Delay+Looper and Looper – press the small white Mode button within the DELAY/LOOPER group.
  • Page 6 1. Connect your expression pedal to the EXP jack. 2. While the EXP MODE button is off, the expression pedal acts like a volume control for your dry signal before it enters the Grand Canyon. 3. While the EXP MODE button is enabled, the expression pedal sweeps all parameters that are assigned to it for the currently selected Delay Type or Looper mode.

  • Page 7: Controls And Leds

    LOOPER Mode: Active when LOOPER LED is lit / DELAY LED is unlit  The Grand Canyon’s delay effects are deactivated in this mode.  The four white knobs control the looper, with their functions listed in the second level of orange text beneath the knobs.

  • Page 8: Control Knobs

    - CONTROL KNOBS - The four knobs on the left side of the Grand Canyon control the main parameters of the delay effects and the looper. These knobs have different functions depending on the current mode. The top row of red labels specifies the delay-specific functions of the knobs, while the bottom row of orange labels specifies the looper-specific functions of the knobs.
  • Page 9 Looper parameters DRY CUT – Works as a reverse volume control for your dry signal. Your dry signal is loudest when the knob is turned down to its minimum or counter-clockwise position. The DRY volume decreases as the knob is turned clockwise.

  • Page 10: Delay Type Knob, Preset Led, And Mini Knobs

    - DELAY TYPE KNOB, PRESET LED, AND MINI KNOBS - DELAY TYPE Knob This knob is a rotary encoder that selects which of the Grand Canyon’s Delay Types is active. The list ranges from ECHO at the top to DOUBLER at the bottom.

  • Page 11: Illuminated Buttons

    EXP MODE Button – When this button is lit, EXP MODE is enabled. When an external expression pedal or control voltage is connected to the EXP jack on the rear of the Grand Canyon, you can control any combination of knob parameters with your foot. When the EXP MODE button is disabled (button is not lit), the external expression pedal acts as a volume pedal for the dry signal and the signal into the delay effect.

  • Page 12: Tap Divide Button And Leds

    - TAP DIVIDE BUTTON AND LEDS - The TAP DIV function sub-divides the tempo tapped in via the TAP/LOOP footswitch to create shorter or longer delay times in sync with your tap time. It assumes that what is tapped is a quarter note. TAP DIV then divides the quarter note to produce delay times rhythmically in time with the tap tempo.

  • Page 13: Footswitches And Leds

    When the orange LED in Grand Canyon graphic is lit, the unit is in effect mode. If the MOMENT button is lit, then the Grand Canyon is normally in bypass mode unless you press and hold the BYPASS footswitch, at which point it goes into effect mode.
  • Page 14 Looper Mode Footswitch Functions TAP/LOOP – In Looper mode, the TAP/LOOP footswitch works the same as in Delay+Looper mode. Bypass/Stop – In Looper mode only, press and release the BYPASS/STOP footswitch to stop the loop or begin loop fadeout. If you press the STOP footswitch while in the middle of loop fadeout, the looper immediately ends fadeout and stops the loop.

    ELAY YPE AND ETAILS ECHO – Digital Delay Accurate 24-bit digital delay that offers either lowpass or highpass filters in the feedback loop and a bit crusher effect prior to the delay line. FILTER: Turn this knob counter-clockwise from noon for a lowpass filter and clockwise from noon for a highpass filter.
  • Page 17 MOD – Modulated delay Same digital delay as in ECHO mode but Filter and Bit Crush have been replaced by modulation parameters. MOD RATE: As you turn clockwise, the modulation rate increases. The modulation rate ranges from 0.1Hz to 163Hz. MOD DEPTH: As you turn clockwise, modulation depth increases.
  • Page 18 Organic echoes transform as they repeat while lush modulation—ranging from subtle to oceanic—massages each note. The Grand Canyon also recreates the DMM’s renowned FEEDBACK control, which provides a musical runaway effect when maxed and the ability to bend the pitch of echoes as you turn the DELAY knob.
  • Page 19 By default, the pitch shift block is located outside the delay’s feedback loop, which means each note you play is pitch shifted once and then delayed. The Grand Canyon includes a secondary mode where the pitch shift block can be moved to within the feedback loop for cascading pitch-shifted delays.
  • Page 20 This mode creates a shimmer effect, generating a rich octave-shifted wash of harmony with your guitar. The maximum delay time is 1.5 seconds. The Grand Canyon achieves the Shimmer effect by modeling a chain of four EHX pedals: FILTER: Controls a low pass filter in the feedback path after the Shimmer effect.
  • Page 21 DRUM – Drum Echo Emulates the classic effect of a 60s era magnetic drum echo, complete with a drum age control and equally spaced playback heads to create unique echo rhythms. The delay time is divided by total number of drum playheads.
  • Page 22 DOUBLER – Doubletracking effect Doubler is a short delay, a detuner, and a stereo spread effect that is great for thickening up a mono signal or widening it to stereo. The maximum delay time is 150ms. The delay times of each stereo output may be offset from each other and up to +/-50 cents pitch shift can be applied to the signal.
  • Page 23 LOOPER When the Grand Canyon is in Looper-only mode, the four white knobs change their function to the labels in the second row of text under them. See the CONTROLS section for details on the white knobs in Looper mode.

  • Page 24: Using The Looper Mode

    SING THE OOPER  The LOOPER LED must be lit for all loop functionality.  To record or overdub your loop with delay effects, ensure both the DELAY and LOOPER LEDs are lit. This is Delay+Looper mode.  Cycle between DELAY and LOOPER modes by pressing the small white Mode button.
  • Page 25 5. Overdubbing will never change the length of the loop. 6. The Grand Canyon can overdub indefinitely, allowing you to continuously add new audio to your loop for as long as you like. 7. After finishing an overdub, the Undo/Redo function is enabled. You may undo, then redo the last overdub layer as many times as you like.

  • Page 28: Expression Pedal Use And Setup

    SE AND ETUP The Grand Canyon accepts an expression pedal with TRS plug or control voltage (CV) on a TS plug at its EXP phonejack. Please see page 15 for specifications on acceptable expression pedals and voltage range for the Grand Canyon.
  • Page 29 3. Once the other buttons stop blinking, release the EXP MODE button. EXP MODE will now be blinking at a medium rate. 4. Set any of the Grand Canyon’s six knobs to the position you want them to have at the expression pedal’s heel position. If you do not want a knob to be swept by the expression pedal, do not move it at this point.

  • Page 30: Tap Tempo On The Grand Canyon

    RAND ANYON The Grand Canyon’s delay time can be set with tap tempo using a built-in footswitch or by using an external momentary switch. With either method, you can achieve nine different delay times all in time with your tap tempo using the TAP DIV button.
  • Page 31 3. The BYPASS LED will flash 7 times if tap tempo is disabled. The LED will flash 2 times if tap tempo is enabled. 4. If the Grand Canyon is reset to factory defaults (see page 35), the BYPASS/STOP footswitch’s tap tempo functionality will be enabled in Delay+Looper mode.

  • Page 32: Preset Use And Setup

    RESET SE AND ETUP The Grand Canyon can save and recall one preset per Delay Type plus a preset for Looper mode. Each preset saves all current knob settings, the current Expression Settings, Tap Tempo, Tap Divide, all illuminated button settings, and secondary mode status if you are in Pitch or Drum modes (see page 34).
  • Page 33 CHANGING PARAMETERS AFTER RECALLING PRESETS Normally the PRESET LED lights solid after loading a preset. If you turn a knob, press a button in the top row, or tap in a new delay time, the PRESET LED blinks to indicate that a preset is loaded but has been altered. RELOADING ALTERED PRESETS In the situation where a preset has been altered and therefore the PRESET LED is blinking, press and release the DELAY TYPE knob to recall the preset...

  • Page 34: Secondary Mode Functionality

    Secondary Mode function. PITCH SECONDARY MODE By default, the Grand Canyon is in Standard Pitch mode, where the pitch shift block is before the delay block in the signal chain. In this mode, the pitch shift is outside of the feedback loop, yielding an effect where the delay’s repeats are always the same pitch.
