Klowra Whorl Rotary Effects Pedal

Whorl Rotary: A sonic vortex veiled in the haze.

Whorl Rotary recreates the dimensional movement and modulation of classic rotating speaker systems through detailed physical modeling. Based on detailed physical modeling, it calculates the authentic mass of the treble horn and bass drum to recreate the true 3D Doppler effect through speaker mass simulation.

Whorl Rotary reimagines the psychedelic studio legends of the late '60s. With three precision-modeled cabinet configurations, it feels like a real Vibratone/Leslie running before you. By emulating the mechanical nuance of inertia—with fast/slow switching, a living envelope engine, and expressive braking—it perfectly reproduces the drag and air friction of the rotors.

Whether you crave the classic British psychedelic textures or the swirling blues modulation, Whorl captures every breath of your performance to drive this dynamically responsive physical engine.
