The Red Witch Euphemia Sample Hold Filter is a 100% all analog sample hold filter pedal with a number of unique, controllable parameters1. A sample hold filter shifts the guitar through a random range of frequencies, and Red Witch describes the result as bubbling, mysterious and otherworldly: "There's something magical in that bubbling, mysterious, random range of frequencies"1. The maker also points to a notched bandpass guitar tone associated with players like Carlos Santana and Brian May1.
A numbered Nouveau series run of 59

Controls and the hidden bandpass mode
The pedal carries what Red Witch calls the usual Velocity control, which sets the speed of the filter shift1. Turning the Aggression control fully counter-clockwise unlocks what the maker calls a secret feature: the bandpass filter mode1. In that mode the Frequency dial tunes the guitar to a chosen frequency for a notched tone, the sound Red Witch associates with Carlos Santana and Brian May1.

Circuit lineage
Red Witch traces the design to the analog sample hold pedals of the past: "Oberheim and Maestro spring to mind when thinking of the great analog Sample Hold pedals of the past"1. For players exploring the wider filter family, Euphemia sits alongside other designs on the Filter Pedals type page.
