A complete two-mode Overdrive on channel 2, and a complete Compressor on both channels (Volume, Ratio, threshold, two-mode release).

Aux in for your media player and a separate eq on headphone outputs for perfect monitoring. But not only: parallel output for a clean signal, chromatic tuner, send-return for your effects.
