The Imp is a family of small MIDI mods for guitar, bass and other effects devices. With an Imp it is possible to switch effects devices on and off via MIDI control or handle other switching duties.

There is also the Imp-THRU. An additional PCB to add MIDI Thru functionality or build your own MIDI Thru box.

The brand new Imp-2PDT – MIDI Relay extends the possibilities of the Imp-3PDT by making all relay connections accessible.

Features:

• MIDI controllable switching (bypass, tap tempo, etc.)
• MIDI clock synchronous switching
• MIDI channel is selectable by using the foot switch
• Compatible with all MIDI 1.0 compliant controllers
• True bypass relay circuit with momentary function (only Imp-3PDT)
• Effect monitoring for reliable status (on/off)
• Simple assembly through soldered-on socket or footswitch

MIDI Mod Variants

Modifying with the Imp always depends on whether an SPST (also known as a soft switch) is already built in or a 3PDT true bypass switch is to be replaced. There are two different variants depending on this:

Imp-SPST: For effects that already have an SPST soft switch for bypass and/or tap tempo.
Imp-3PDT: For effects with a conventional 3PDT foot switch.
Imp-2PDT: Like the Imp-3PDT, but with more flexible wiring.
