The Context 2 is a reverb pedal effect. It provides 8 algorithms, including room, hall, cathedral, gated reverb, reverse reverb, plate, spring, and a granular reverb. It also offers stereo input/output, USB MIDI, fully assignable expression pedal, delay plus reverb in all modes, separate high and low frequency damping controls, modulation and other useful features. The basic functions can be easily controlled by potentiometers. The Context 2 requires a 9 V center negative power supply (not included).
