From the project
Effects pedals and stomboxes
Route certain frequencies through a different effects chain.
1. Cutoff (7Hz to 7kHz) 2. Send mode switch (highs, all, lows) 3. Wet/Dry mix 4. Bypass switch
When bypassed (4), IN is connected to OUT (true bypass) and the device is powered off.
This mode can be used to turn a separate parallel effects chain on and off. Mix (3) is a wet/dry blend.
IN is sent to SEND. IN and RECV are mixed and sent to OUT. Cutoff (1) has no effect.
