Earthquaker A/B Box

The EarthQuaker Devices A/B Box is a simple tiny tool that lets you choose between two of pretty much anything. Because of its completely passive design, there is no circuitry between the input and outputs which means it can be use in both directions. Use it to switch between two amps! Switch between two channels on a multi-channel amp! Use it as tuner out/mute switch! Switch between two instruments! Run a dry path and a wet path! The time to passively choose is now!
