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. 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 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.
