An immaculate example of the Fredric Effects Warp Sound.
The Fredric Effects Warp Sound is a modernised version of the rare 1970s Vorg Warp Sound, a particularly interesting filter+distortion effect. It is an exact reconstruction of the original circuit, improved by moving the internal distortion control to the outside of the enclosure. This useful gain control makes the Warp Sound much more versatile, and moves it into fuzz territory with the gain turned-up.
