Outside The Box FX is a small American maker of experimental, hands-on signal-routing devices, with products fulfilled through Cusack Music in Holland, Michigan. The brand is best known for the Signal Diverter, an external pass-through router that breaks the hot side of a guitar signal out to two clip-tipped leads — clip them to anything conductive and the object becomes part of the circuit, letting players run their tone through fruit, soda cans, found metal, other people, or whatever else completes the loop.

Its companion product, the Jumper Cables, takes the same idea further by routing both the positive and negative sides of the signal out to insulated clips with true-bypass switching, giving experimenters more flexibility for interfacing with external objects and devices. Both pieces are built with heavy-duty enclosures and a 9V-powered indicator light, and they sit firmly outside the standard distortion/modulation/delay pedal world — there is no traditional electronic effect circuit inside, just a clever way to make the surrounding world part of the audio path.

The catalog is intentionally narrow and the brand has a cult, novelty-leaning reputation among pedal hobbyists and YouTube demo channels who have showcased the Signal Diverter run through unusual conductive objects. Distribution is handled in part by Full Effect Distro, with the Signal Diverter also sold direct through Reverb.

Outside The Box FX has 2 products cataloged on Equipboard, including Switch Effects Pedals. Their gear is featured by 2 artists, with the strongest followings in Rock, Blues, and Folk, World, & Country. Notable users include Steve Onotera and samuraiguitarist.
