As one of the leading innovators in pedalboard technology, One Control continues to listen to the working studio and performance professionals like guitarist Josh Smith. The One Control Minimal Series MIDI Solo Stereo Loop (SSL) unit was created by his request for a small MIDI controlled stereo loop pedal to help tame his rig. The SSL provides a simple method to expand pedals with a MIDI controller/switcher. The side encode switch allows musicians to assign MIDI channel 1 to 4 to the loop, the relay based design ensures the minimum signal loss.
