FS-7 LESLIE QUEEN Phase Shifter
The Guyatone FS-7 Leslie Queen Phase Shifter is an exceptionally rare, vintage analog effects pedal manufactured in Japan during the mid-1970s. Designed to replicate the immersive, swirling sounds of a rotating Leslie speaker cabinet, it is highly prized by collectors for its lush, organic modulation. The pedal features a large, robust chassis with a distinctive vintage aesthetic and is equipped with separate speed settings for Slow and Fast modes, allowing musicians to toggle between different intensities of the effect. Technical controls typically include four switches that manage Normal/Effect, Fast/Slow, Vibrato/Leslie Tone, and Shallow/Deep settings, providing significant tonal flexibility. It functions well with guitars, keyboards, and organs, delivering a characteristic 1970s phase-shifted sound. Due to its early production and limited availability, the FS-7 is considered a landmark piece of Japanese pedal history, often appearing under the "Rolly Queen" moniker in later iterations while maintaining its core rotary-inspired circuitry.
