Volume
In
Controls the level of sound coming into the Rack Extension.
Out
Sets the output level of the Rack Extension.
Blend
Controls the dry/wet balance. Fully left, the unmodified input signal is passed through.
Fully right, only the processed signal is heard. Points in the middle give you a mix of
both.
Crunch
A not-so-subtle wavefolding effect at the end of the delay signal chain. Low settings add
saturation to the echoes, and high settings completely transform the delay tail. Since
wavefolding is based on signal amplitude, Crunch’s effect will change over time as
echoes decay.
