The Fredric Effects Deeply Unpleasant Companion Mk1 is a replica of the vintage Shin-ei FY-2 and FY-6 fuzz pedals. It is built using the correct 2SC828 transistors to accurately recreate the original sound. The pedal has controls for Fuzz and Volume, and a switch to toggle between the smoother Fuzz Companion (FY-6) and the more aggressive, spitty Unpleasant Companion (FY-2) sounds. It also features a useful LED indicator and standard DC power input, improvements over the original vintage pedals.
