Acidbox III Key Features
Powerful stereo analog filtering
Inspired by the Polivoks filter, Acidbox III delivers an aggressive, textured sonic character. Stereo analog filtering adds immediate depth to any audio signal, mono or stereo.
Exclusive audio overdrive
An internal saturation circuit provides a warm, dirty grain, ideal for rough bass, acid leads and rich percussive textures. The sound becomes as alive, warm and rough as you like.
Intuitive modulation
The synchronizable LFO features 8 waveforms and a tap tempo function for easy synchronization with other equipment. The envelope follower adapts the modulation to the intensity of the playing or the incoming signal.
Extended control and connectivity
Control the cutoff frequency manually, via CV or remotely via a configurable input (expression, footswitch, external LFO...). Full compatibility with studio or stage setups.
Robust, adaptable design
Its compact, sturdy aluminum case integrates perfectly into any configuration. Adjustable input gain enables compatibility with guitars, synths, grooveboxes and more.
A versatile creative tool
Perfect for DJs, live musicians or producers, the Acidbox III can transform complex stereo sounds or add grit to a simple mono line. It quickly becomes an essential creative tool.
Acclaimed sound quality
Selected as one of the best studio effects, the Acidbox III has won over the specialist press thanks to its sonic power, versatility and assertive analog character.
