The TT-2 is compatible with a large range of digital amps, effects units, MIDI controllers and stomp boxes that support external foot switches. The TT-2 features a resilient metal chassis, and two momentary foot switches with a small click action for tactile feedback. The TT-2 is switchable between TRS and TS mode. TRS mode supports two switches on a single cable compatible with devices such as the Line 6 HX Stomp, DL4 Mk2, Eventide H9, Fractal Audio MFC, and RJM Mastermind. In this mode you can connect both switches to the device with just a single TRS cable, removing the need for Y cables or adapters.
