Product Description

Klowra KBB08 Whorl Dynamic Rotary Speaker Pedal

The Klowra Whorl is an ultra-compact digital rotary speaker simulator designed for players who crave the lush, swirling movement of a vintage dual-rotor cabinet without the back-breaking weight. Part of Klowra’s Budding Bloom Mini Series, the Whorl utilises an advanced three-dimensional modulation engine that models the complex acoustic interactions of physical spinning horns and drums, providing an incredibly immersive, chewing swirl that reacts organically to your performance.

Authentic Dual-Rotor Emulation and Balance

At the heart of the Whorl is a sophisticated algorithm that models separate bass drum and treble horn rotation speeds. The dedicated BAL (Balance) knob lets you dial in the exact crossfade ratio between the low-frequency drum throb and the high-frequency horn sparkle. Paired with the interactive RATE control, you can effortlessly sweep from a slow, atmospheric chorale shine to a lightning-fast, warbling tremolo texture that breathes new life into chords and solo passages alike.

Tri-Mode Mechanical Enclosure Voicings

To expand your sonic palette past a standard vintage cab setup, the Whorl features a dedicated MODE selector button that instantly swaps between three highly distinct cabinet emulations:

  • Classic (White LED): Delivers a warm, woody 122-style cabinet tone with rich mid-range presence and a smooth mechanical ramp, ideal for classic blues and rock organ textures.
  • Modern (Blue LED): Emulates a high-powered, clear solid-state rotary cabinet with wider high-end response and a deeper, highly pronounced physical swirl.
  • Vibrato (Orange LED): Focuses the algorithm heavily into scanner-style pitch modulation, creating a watery, experimental psych-rock texture.

Adjustable Acceleration and Multi-Stage Tweaks

Recreating the dynamic thrill of a true mechanical speaker system requires control over inertial lag. The Whorl includes a three-way ACC (Acceleration) toggle switch that dictates how quickly the virtual motors transition between fast and slow settings. Combined with the comprehensive TWEAK parameter knob, players can fine-tune hidden acoustic interactions like microphone distance, internal cabinet resonance, and structural drive to perfectly adapt the swirling effect to their rig's overall character.

High-Fidelity DSP and Performance Control Hookups

Driven by Klowra's high-headroom WildSeed Engine, the Whorl boasts pristine 24-bit AD/DA converters alongside a 32-bit floating-point DSP block to retain the full frequency spectrum of your instrument. Holding down the heavy-duty main footswitch triggers an instantaneous speed change override, letting you perform hands-free dynamic acceleration shifts on the fly. Complete with switchable True or Buffered Bypass pathways, a dedicated CTRL input jack for remote momentary footswitch control, and a USB-C port for ongoing firmware optimisations, the Whorl delivers a giant studio sound in a pocket-sized package.
