Erica Synths Acidbox III Is Here – Stereo Polivoks VCF Sound, Tabletop Format

Being big fans of the original Acidbox (see our Acidbox feature), this is really exciting news! Erica Synths Acidbox III brings you the core of the famous Polivoks VCF in stereo version with unique audio signal overdrive circuit, built in LFO and envelope follower in a compact, full aluminium case.

Watch the Acidbox III demo video (it’s fun!):

The Acidbox III has adjustable input gain, therefore it works with various sound sources – guitars, units with line level signals (synthesizers, grooveboxes, etc.) and modular synths.

Configurable control input allows you to connect a bypass footswitch, expression pedal, external cutoff control voltage source and LFO synchronization trigger.

This makes the Acidbox an ideal companion in almost every production or live performance setup.
