Klowra Whorl Rotary effect pedal

General

With the Klowra Whorl Rotary, you give your playing the swirling motion of a classic rotary loudspeaker. This digital effect pedal uses physical modeling to mimic the movement, mass, and inertia of the tweeter horn and bass drum. This provides not only modulation but also the characteristic Doppler effect and gradual speed changes of such a mechanical system. Think of psychedelic sounds from the late sixties or a rotating blues tone. RATE sets the rotation speed, while BAL determines the volume ratio between the bass drum and horn. The accompanying indicator flashes in sync with the horn's speed: handy during adjustment.

Three sound characters, three ways of playing

The Voice switch offers three sound characteristics: a balanced rotary sound, the fuller bass response of a larger cabinet, or the more spacious impression of a microphone placed further away. Additionally, you can choose from three operating modes. RPM Step lets you switch between two speeds, Spin responds to your playing dynamics, and Brake gradually brings the virtual rotors to a stop. The TWEAK button is assigned a different task each time: setting the second speed, trigger threshold, or brake duration. With ACC, you determine how quickly speed transitions occur. Hold down the built-in footswitch for the assigned function, or use an external TS momentary footswitch via CTRL. This allows you to adjust the movement directly while playing.

Compact pedal with extensive signal processing

Under the hood, Klowra's WildSeed Engine features 32-bit floating-point DSP and 24-bit AD/DA conversion. You connect the pedal via a mono 6.35 mm TS input and output. You can choose between true bypass and buffered bypass, depending on your preference and pedal setup. The soft-touch relay circuit ensures silent switching, while the compact housing saves space on your pedalboard. Firmware updates can be performed via USB-C. A 9V DC power supply is required for use; power consumption is 150 mA. The Whorl belongs to the Budding Bloom series, featuring hand-drawn, psychedelic illustrations centered around Asian mythological creatures and sacred objects. Consequently, its appearance also has a distinctive character.
