Overview of EarthQuaker Devices LTD Edition Aurora Borealis Avalanche Run Stereo Reverb & Delay w/ Tap Tempo Guitar Pedal

Accepting pre-orders now, shipping out mid-January 2024.

Have you always dreamt of seeing the Aurora Borealis? Today is your lucky day!  While we wish we could fly every one of you first class to Norway, we can offer you the next best thing (or the next best thing to that best thing) - a limited edition Aurora Borealis Avalanche Run!

The Avalanche Run is a dreamy stereosonic exploratory multi-tool that includes up to 2 seconds of delay time, reverse delay, tap tempo with subdivision control, switchable true bypass or buffered bypass with 5 different tail lengths (including a sound-on-sound style lo-fi looping mode) and an assignable expression control that maps the expression jack to a control of your choice, including the toggle! The delay section allows tweaking from tape emulation to bucket brigade styles with a twist of the wide-range Tone control. The cavernous, plate-style reverb has just a touch of modulation similar to the one found in our precious Dispatch Master only more lush with an adjustable Decay. Otherworldly reverse delay and dynamic swelling reverb settings are accessible through a 3-way toggle switch. And that’s just the beginning...

CONTROLS:

1. Time: This controls the delay time and goes from 0ms to just under 2000ms.

2. Repeats: Controls the regeneration of the delay, from zero repeats to near infinite.

3. Tone: Controls the tone for the delay line only. Roll off highs to the left, roll off lows to the right and get a flat response in the middle.

4. Mix: The is the volume control for the delay line. This blends in the wet with dry until 1 o’clock, 1 o’clock to 3 o’clock boosts the wet signal over the dry and 3 o’clock up brings down dry until it is fully wet when all the way up.

5. Expression Jack Assign Switch: Use this switch to map the expression jack to one of the assigned controls.

• Decay: Controls the reverb decay length

• R Mix: Controls the reverb mix

• Time: This takes over for the delay time control and is DRASTICALLY different than the interface control. Using the expression pedal to control the time will give you all kinds of wild effects that can not be achieved by turning the knob.

• Repeats: Controls the delay repeats

• D Mix: Controls the delay mix

• Toggle: This takes over for the toggle switch and will cross fade from forward delay in heel down position to reverse delay in toe down position.

6. Ratio Selector Switch: Selects delay subdivisions when time is set by the “Tap” switch.

• 1/1: Quarter Note

• 3/4: Dotted 8th

• 2/3: Quarter Note Triplet

• 1/2: 8th Note

• 1/3: 8th Note Triplet

• 1/4: 16th Note

7. Decay: Controls the decay length of the reverb, short decay counterclockwise, long cavernous decay clockwise.

8. Toggle Switch (Mode Selector)

Normal: This is the “standard” delay and reverb mode

Reverse: This is reverse delay mode with “standard” reverb

Swell: This is the volume swell mode

9. Mix: This is the volume control for the reverb. Blends in the wet with dry until 1 o’clock, 1 o’clock to 3 o’clock boosts the wet signal over the dry and 3 o’clock up brings down dry until it is fully wet when all the way up.

Expression Jack
The expression jack is located on the west side of the pedal. It is a TRS jack with the tip acting as the wiper. We recommend using a Moog expression pedal with the output adjustment knob all the way up. We cannot guarantee any other expression pedal to work with the Avalanche Run.

Flexi-Switch® Technology
This device features Flexi-Switch® Technology! This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

• For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

• For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.

Power
This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!

PCBs are populated by a combination of artificial and human intelligence in the Akron, Ohio of America.
Each and every Avalanche Run is completely assembled, wired and tested by total human beans in the tiny tundra town of Akron, Ohio.
