The Boss DS-2 Turbo Distortion with Remote features twin Turbo modes! Mode One produces warm and mellow distortion with flat frequency response. Mode Two provides a biting distortion with a midrange boost that's great for leads. The built-in remote jack on the Boss DS-2 Turbo pedal allows you to connect to an external footswitch such as the FS-5L for instant, handsfree mode switches.
