PSP stompFilter is a creative tool designed to provide an exceptionally wide range of modulated filters and gain sounds.

PSP stompFilter effects include a simple LFO-modulated low-pass filter; auto-wah; low-pass, band, or high-pass filter; and compressor. Thanks to the smoothly adjustable filter type and flexible LFO cross-modulations by the signal envelope, PSP stompFilter can provide vivid and expressive filtering. Just a touch of adjustable LFO randomization will provide analog-like "imperfections," ensuring you'll never get bored.
