PSP stompFilter is a creative tool designed to provide an exceptionally wide range of modulated filter and gain sounds. Its effects include a LFO-modulated low pass filter; auto-wah; low, band, or high-pass filter modes; and a compressor. Thanks to the smoothly adjustable filter type and flexible cross-modulations of the LFO by the envelope detector, PSP stompFilter is able to provide vivid, expressive filtering. Just a pinch of adjustable LFO randomization will provide analog-like „imperfections,‟ ensuring that you will never get bored of it.
