User Guide

Reverse
• Reverse delay, normal reverb.
• Ratio is always in 1/1 position no matter where the ratio switch is set.
Pro Tip: The other ratios will still work for standard delay, if you set
the ratio for anything other than 1/1 when you are in Reverse mode,
you will get really cool rhythmic patterns when using the Tap switch or
expression pedal to switch between reverse and “normal” modes.
• Hold down the Tap switch to temporarily send the delay back to forward
mode and release the Tap switch to go back to Reverse.
Pro Tip: Use the expression pedal in the “Toggle” position to go back
and forth from reverse to standard. This allows you to still use the Tap
switch to send the delay into self-oscillation.
Swell
Adds an auto swell to the entire signal path, much like slowly turning
up the volume control on your guitar.
• Reverb Mix controls the length of the swell, swell length becomes
longer as you turn the control clockwise.
• Swells are triggered by the input, regardless of input strength. To get
the most from this effect, adjust your playing to a more staccato style
and mute the strings after every note or chord.
• This mode sums both left and right inputs on both the wet and dry
paths to mono.
• Hold Tap switch down to send delay into innite repeats. On shorter
Time settings, they will quickly go into oscillation and on longer Time
settings, they will slowly build.
Tails Mode
The Avalanche Run also has a “Tails” mode. Tails mode allows the wet
signal to naturally fade out after the effect is switched off. It has 5 Tail
length settings that are selected by the Ratio switch during power up.
How to engage Tails mode:
• Unplug the power cable
• Set the Ratio switch to the desired Tail length:
• 1/4- True Bypass (See “Return to True Bypass” below)
• 1/3- Short Tails
• 1/2- Medium Tails
• 2/3- Long Tails
• 3/4- User Dened- Tail length is determined by where
the repeat control is set. Tails can go into oscillation
by holding the Tap switch down or stopped by double
clicking the Tap switch.
• 1/1- “Sound on Sound”- Tail length goes into innite
repeats once the effect is switched off. Tails can be
stopped by double clicking the Tap switch.
• Once you have selected the Tail length, hold down the Activate
switch and plug in the power. The Activate LED will light up Green
after 2 seconds then release the Activate switch and you’ll be in your
desired Tails mode.
• The signal is in buffered bypass mode when the LED is green.
• The ratio switch will go back to selecting your desired Ratio after this
process is complete.
Return to True Bypass mode
• Unplug the power cable
• Set the Ratio switch to 1/4
• Hold Activate switch and plug in the power. The Activate LED will light
up Red after 2 seconds and you’ll be back in True Bypass mode.
Jacks & Signal Path
The audio jacks are located on the north side of the pedal, along with
the 9v 425ma power jack.
• The Avalanche Run has a stereo analog dry path, a dual mono delay
path and a stereo reverb.
• To run mono; use the left input and output only.
• To run stereo; through use both left and right inputs and outputs.
• To run mono in and stereo out; use the left input and both left and
right outputs.
Cool Trick: Plugging into the right input and using the left and right
outputs will give you an all-wet left channel and a standard mixed right
channel while the effect is engaged. You can create dramatic stereo
effects by keeping the Mix set low and turning up the amplier source
connected to the left output. The left output will not pass dry signal
when the effect is turned off in true bypass mode but trails mode it will
still produce the effected signal as long as it is set to decay.
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.
