Erica Synths Acidbox II

The Erica Synths Acidbox II is a tabletop emulation of the notorious Russian synthesizer’s VCF, renowned for its acidic squelches and deep analog basslines. The tabletop module utilizes similar Russian ICs to those used in the original Polivoks VCF, making it easy to recreate specific tones with tactile control options. 

The Acidbox II contains significant revisions compared to the first, including redesigned LFO, built-in analog noise generator, and balanced outputs.
