Klowra Whorl Rotary – Dynamic Rotary Speaker Pedal

The Klowra Whorl Rotary faithfully recreates the spacious sound and movement of classic rotary speaker cabinets using advanced physical modeling. By accurately simulating the inertia of both the rotating horn and bass rotor, it delivers convincing Doppler effects and immersive three-dimensional modulation.

Three distinct cabinet voicings provide a wide range of rotary tones, from warm vintage textures to modern, vibrant modulation. Dedicated controls allow precise adjustment of rotor speed, acceleration, horn and drum balance, and other performance parameters.

An intelligent Auto Spin function dynamically responds to your playing, adding natural movement and expression, while authentic Fast, Slow, and Brake transitions recreate the behavior of a real rotary speaker.

Featuring premium DSP processing, switchable True or Buffered Bypass, USB-C firmware updates, and support for an external footswitch, the Whorl Rotary is equally suited for live performance and studio recording.
