From the vendor

New for 2020

New Channel Switching Mode added for multi-effects combination builds

Includes

• Relay Bypass PCB

• Pre-programmed microcontroller

Footswitch, relay, and other components are not included

Features

• Uses latching relay (not included) for lower power consumption

• Grounds PCB input in bypass to reduce noise

• I/O pinout directly interfaces with most PedalPCB projects

Instant Momentary Mode

• Tap footswitch to toggle between active / bypass (standard operation)

• Hold down the footswitch while the pedal is bypassed to momentarily activate the effect until the footswitch is released

• Hold down the footswitch while the pedal is activated to momentarily bypass the effect until the footswitch is released

Auto Power-On Mode

When Auto Power-On Mode is enabled the pedal will automatically engage when power is applied. This is useful when the pedal is rack mounted or used with a loop bypass system.

Channel Switching Mode

Channel Switching Mode is designed for use in multi-in-one combination effects pedals. When Channel Switching Mode is enabled only one effect can be active at a time.

Pressing any footswitch automatically activates that effect and bypasses any other active effect on the same control bus. Pressing the active footswitch again bypasses the effect.
