Erica Synths Acidbox III – Stereo Analog Filter Inspired by the Polivoks
The Erica Synths Acidbox III integrates the soul of the famous Polivoks filter in a stereo version enhanced with a unique audio overdrive circuit, a synchronizable LFO, and an envelope follower, all in a robust and compact aluminum enclosure. Designed for musicians, producers, and live performers seeking powerful, dirty, and expressive analog textures.
Highlights
Stereo analog filter (Lowpass/Bandpass) based on the original Polivoks circuit
Proprietary audio overdrive circuit for a rich, saturated sound
Synchronizable LFO with 8 waveforms and tap tempo function
Envelope follower with integrated modulation attenuator
Manual and CV control of the cutoff frequency
Configurable control input (expression pedal, footswitch, external LFO, etc.)
Adjustable input gain to adapt to any type of audio source
Durable aluminum housing with a compact design
Maximum versatility
Thanks to its adjustable input gain, the Acidbox III adapts to a multitude of sources: guitar, synthesizers, grooveboxes, DJ machines, and even modular systems. Its customizable control input allows remote control of key functions (bypass, cutoff, LFO sync)—ideal for both studio and stage use.
An effect with a strong character
“A pronounced analog effect, even more versatile thanks to its stereo processing and modulation options.”
— Future Music Magazine (Selection of the best studio gear 2018)
“The Polivoks filter has a real personality, very dirty, with a lot of charm. A valuable tool in the studio as well as live.”
— MusicTech Magazine (Rating: 9/10)
For all styles, all configurations
The Acidbox III shines as much in a DJ setup, for dynamic real-time filtering, as in a live musician's rig, where the envelope follower can shape the sound according to the intensity of the playing. Whether you're looking to color a mono bass, saturate a vocal, or transform a stereo synth, the Acidbox III is a creative companion of choice.
