AcidBox III Desktop Polivoks VCF

Erica Synths AcidBox III

The latest incarnation of the Erica Synths AcidBox mobilizes the core of the infamous Polivoks VCF, albeit in stereo and alongside an optimal feature set consisting of a unique overdrive circuit, syncable LFO, an envelope follower, and both manual and remote control over the filter cutoff.

The AcidBox was designed for use with a wide variety of audio sources, particularly guitars and line level sources. Lending to this orientation is a configurable control input that lets users connects a bypass footswitch or expression pedal, adjustable input gain, and an LFO sync trigger. All of this and more makes the AcidBox III ideal for both the studio and the stage.
