QUICK START GUIDE PLUGGING IN THE GRAND CANYON 1. Connect the supplied EHX9.6DC AC Adapter into the 9V jack at the top of the Grand Canyon. Plug the AC Adapter into an AC outlet. 2. Connect your guitar or other instrument into the INPUT jack using a standard 1/4” instrument cable. Connect the L OUT jack to your amp with another standard 1/4” instrument cable. 3. For stereo operation, connect R OUT to another amp. DIALING IN A STANDARD DIGITAL DELAY EFFECT 1.
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. 3. If you want to record a loop with the Grand Canyon’s internal delay effects, make sure both the DELAY and LOOPER LEDs are lit. 4. If you want to record a loop without the Grand Canyon’s effects, only the LOOPER LED should be lit. 5.
USING AN EXPRESSION PEDAL 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. 4. You may assign any knobs you like to be swept by the expression pedal.
CONTROLS AND LEDS - DELAY / LOOPER MODES, BUTTON, AND LEDS The Grand Canyon has three functional modes: Delay, Delay+Looper, and Looper. To the right of the DELAY knob there is a small white Mode button and two LEDs labeled DELAY and LOOPER. Pressing the Mode button cycles you through the three modes, allowing you to seamlessly integrate delay effects into your looping. You can also use an external footswitch to move between modes; see page 27 for more details on external footswitches.
- 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.
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. LOOP LVL – Controls the output volume of the looper’s playback. Note: In Delay mode, this knob is only active if a loop was already playing before switching to Delay mode.
- 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. One preset can be saved for each Delay Type and for the looper using the DELAY TYPE knob. Press and hold DELAY TYPE to save a preset in the currently selected Delay Type, or for the looper while in Looper mode.
- 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.
- 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. The current DELAY knob setting can also be divided by the TAP DIV button. When you turn the DELAY knob, the range is always based on a quarter note length.
- FOOTSWITCHES AND LEDS The Grand Canyon’s two footswitches have different functions depending on the current mode. The red labels describe the Delay-specific functions of the footswitches, while the orange labels describe the looper-specific functions.
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.
CONNECTIONS INPUT Jack – This ¼” jack is the audio input to the Grand Canyon. The input impedance is 2M. L OUT Jack – Use this output for a mono setup. In a stereo setup this is your left output. The output impedance is 550. R OUT Jack – This is the right output jack in a stereo setup. The output impedance is 550. FSW Jack – Connect an external momentary footswitch to this ¼” jack.
DELAY TYPE AND MINI KNOB DETAILS 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. The lowpass filter attenuates high end while the highpass filter attenuates low end. Starting from the noon position, as you turn counter-clockwise, the cutoff frequency goes down.
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. At fully counter-clockwise, mod depth is 0. MULTI – Multi-tap delay A multi-tap delay where the FEEDBACK knob sets the exact number of echo repeats from 1 to up to 31.
DMM – Deluxe Memory Man A faithful emulation of the EHX Deluxe Memory Man, expertly reproducing the beloved tone of the classic bucket brigade analog delay. 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.
PITCH – Pitch-shifted harmonic delay Pitch shifts your signal before it is delayed. See the charts below for the available intervals. 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. See page 34 for more information on secondary modes.
SHIM – Shimmer 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. As you turn the knob counter-clockwise, the tone of Shimmer first warms up and then becomes muted.
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. For example: if the delay time is 1200ms in 4-Playhead mode, each playhead is spaced 300ms apart. In the secondary 3-Playhead mode they are 400ms apart.
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. The delay time range of the DELAY knob is 0 to 50ms. TAP tempo and TAP DIV functions are not available for DOUBLER.
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. The two mini knobs also provide looper functions: REVERSE: This knob acts like a switch that changes the direction of loop playback. Turning the knob down, fully counter-clockwise, reverses the loop’s direction.
USING THE LOOPER MODE 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. Jump directly from Looper to Delay+Looper mode by double-tapping the Mode button. Doing so does not stop loop playback or overdub. RECORDING A LOOP 1. Ensure no loop is in memory — The MEM LED is off. 2.
5. Double-tap the TAP/LOOP footswitch during fadeout and the loop stops playback immediately. 6. In Looper-only mode, pressing the BYPASS/STOP footswitch during fadeout immediately stops the loop. RECORDING AN OVERDUB 1. To record an overdub, the loop must first be playing. See the STARTING LOOP PLAYBACK section above. 2. While a loop is playing, press the TAP/LOOP footswitch once. Both the REC and PLAY LEDs light to indicate you are in Overdub mode.
ERASING A LOOP 1. To erase a loop, playback must be completely stopped. See STOPPING LOOP PLAYBACK on page 24. 2. Press and hold the TAP/LOOP footswitch for 2.5 seconds to erase the current loop. The REC LED blinks rapidly for half a second just prior to completing loop erase. 3. The MEM LED shuts off, indicating that the loop is erased. 4. Note: the Erase function is final and cannot be undone. Erase is only available when a loop is in memory, as indicated by a lit MEM LED.
EXTERNAL FOOTSWITCH FUNCTIONALITY The Grand Canyon accepts a single momentary footswitch (with TS plug), or a double or triple footswitch (with TRS plug) at its FSW jack. The following chart describes the functions for each footswitch depending on the current mode of the Grand Canyon. When using a single momentary footswitch, the “TIP SWITCH” functions are available.
EXPRESSION PEDAL USE AND SETUP 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. An expression pedal has one function when the EXP MODE Button is off, and a different one when the button is on. EXP MODE Button Off – When the EXP MODE button is not lit, the expression pedal works like a volume pedal placed before the Grand Canyon.
CREATING CUSTOM EXPRESSION SETTINGS Your Grand Canyon comes set up from the factory with some useful Expression Settings for each Delay Type, but you might want to create your own. Here’s how to create custom Expression Settings: 1. Turn the DELAY TYPE knob to select the delay mode for which you want to create a custom Expression Setting. 2. Press and hold the EXP MODE button. After one second, the other illuminated buttons (such as TAILS) will blink. 3.
TAP TEMPO ON THE GRAND CANYON 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. Pressing TAP DIV cycles through the nine subdivision options, each indicated by a combination of LEDs. When TAP DIV is in use, the currently selected TAP DIV LED(s) blink at a rate equal to the current delay time.
You can also disable the BYPASS/STOP footswitch’s tap tempo function in Delay+Looper mode. To disable/enable this function: 1. Unplug the Grand Canyon from power. 2. Press and hold the BYPASS/STOP footswitch while plugging power back in to the Grand Canyon. 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.
PRESET USE AND SETUP 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). Presets do not save loop audio. SAVING PRESETS TO A DELAY TYPE The Grand Canyon must be in either Delay or Delay+Looper mode to save a Delay Type preset. 1.
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 for the current Delay Type or the Looper mode.
SECONDARY MODE FUNCTIONALITY The Grand Canyon contains an additional secondary mode for the PITCH and DRUM Delay Types that can be accessed through a “hidden” 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.
RESTORING FACTORY SETTINGS To restore the Grand Canyon to factory default settings, press and hold the DELAY TYPE knob while plugging power into the Grand Canyon. 1. Unplug the Grand Canyon from power. 2. Press and hold the DELAY TYPE knob while plugging power back in to the Grand Canyon. 3. The PRESET LED will flash 7 times. You can release the DELAY TYPE knob once you see this LED flashing. 4.
