Pigtronix - Keymaster

The Keymaster intuitively impedance-matches inputs and outputs, and with its two effects loops, enables you to connect and combine gear in new, creative ways.
Pigtronix’s Keymaster is one of those devices, which, in itself, doesn’t process sound. As a universal signal-routing device, what it does instead is enable you to get a whole lot more out of the gear you already own. You can convert mic or line-level signals to instrument level – balanced to unbalanced, and visa versa. You can get any signal into a group of guitar pedals (or other processors) and then back out again. Or, as it happens, into two groups of guitar effects; there are two unbalanced pedal-level effects loops – both with true-bypass switching. And you can either alternate between loops or crossfade between them to create a blend of effects. w/ box + power supply
