The Harvestman (Industrial Electronics) Black Locust

This is a very cool utility module that allows you to integrate modules and pedals, or to send external instrument output into your modular rack. Very flexible and useful. I love it and am only selling because I needed the rack space (replaced it with a Boredbrain INTRFX, which is off-rack). There is a little wear around the mounting holes. Comes in original box, with original manual and a set of four Befaco M2.5 knurlies.

From the manufacturer:

Using a compact arrangement of TRS insert sockets (cables not included), Black Locust properly attenuates and amplifies signals to incorporate your guitar effects into the modular system. A return gain control and a wet/dry mix knob condition the effected signal for maximum utility in a modular context. Instruments such as electric guitars and basses can also be patched directly into the module.
Black Locust is the first of three modules in the feedback console series. With no external input signals, the four pedals can operate in a closed feedback loop, self-generating audio signals that are impossible to directly control - only influence. This module is a gateway to this highly experimental patching technique. Further modules in the feedback console series include a matrix mixer and programmable quad VCA/envelope follower/signal router, each designed to expand the Black Locust for deeper exploration of the feedback technique. You will quickly discover sounds that you will never hear again.

Specs:
• 4 channels of guitar pedal interface
