Like the MODERN FUZZ plug-in, the MODERN FUZZ DELUXE plug-in expands the tones available in this plug-in by adding two additional types of clipping. With the jumper set in the DIST (distortion) position, the clipping is smoother and with more headroom. With the jumper set in the OD (overdrive) position, the clipping is smoother still and has the feel and vibe of a vintage overdrive.
