Erica Synths Acidbox III – Stereo Polivoks Filter with Grit and Modulation

The Acidbox III distills the raw, iconic Polivoks filter into a compact desktop powerhouse. This stereo analog filter, complete with envelope follower, syncable LFO, and expressive overdrive, brings gritty character, hands-on modulation, and flexible control to any signal chain—stylized and performance-ready by Soundium.

Key Features

  • Stereo Polivoks VCF: Authentic low-pass/band-pass filter using original-inspired op-amps for rich, uneven resonance in each channel
  • Overdrive circuit: Warm to aggressive saturation via drive and input gain controls
  • Syncable LFO with eight waveforms: Shape filter movement with tap-tempo and divider/multiplier control
  • Envelope follower: Modulates cutoff based on input dynamics, adjustable for depth and polarity
  • Manual and CV control: Cutoff frequency adjustable via knob, CV input, or configurable control input
  • Configurable control input: Assign to footswitch bypass, expression pedal, external LFO, or cutoff CV
  • Adjustable input gain: Accommodates guitars, line-level synths, grooveboxes, or modular sources

Customer Benefits

Acidbox III brings character and modulation to your tone without requiring patch cables.
