Mission Engineering


The Mission TT-Pro integrates two soft touch momentary switches and an expression control knob into a single 4″ x 2″ all aluminum unit. The TT pro is ideal for adding extension switch and expression control to MIDI floor controllers, rack mount digital amps and effects when space and weight are at a premium. The switches would typically be used for functions such as tap tempo, tuner, and looper control. The expression control can be connected to any TRS expression pedal input and the knob be used to control values such as delay repeats, volume etc.

The TT-Pro rear panel includes two individual TS outputs for each switch, plus a combined TRS output that lets you connect both switches with a single cable to a device that supports it such as the Fractal Audio Systems MFC-101 MIDI controller. Using a TRS cable for the switch reduces the cable count and space taken up on your board. The expression control output can be connected to most TRS expression pedal inputs allowing the use of the knob at the center of the TT-Pro to be used to control variable parameters. Multiple TT-Pro units can be used where sufficient switch and expression pedal inputs are available.

The Mission TT Pro is built in a high quality all aluminum box with a mirror polished finish to provide a road ready and great looking space saving solution for your pedal board.
