Luck Duck Pedals
The 8-bit duck is an analog sample rate reducer, which turns your signal into a bit crusher sort of sound. It uses a carrier frequency to set the pitch and drive the "crushed" signal, which can be tuned with the "bit" and "res" knobs. This has the effect of reducing the quality of your guitars sound to NES and telephone quality rates. This effect is more subtle and usable than most "ring mod" type effects.
