PSP stompFilter is a creative tool designed to deliver an exceptionally wide range of modulated filter and amplification sounds. Its effects include a low pass filter with LFO modulation; auto-wow; low-pass, band-pass or high-pass filter modes; and compressor. With a continuously adjustable filter type and flexible LFO cross-modulations with an envelope detector, the PSP stompFilter provides bright and expressive filtering. Just a pinch of adjustable LFO randomization will provide analog “imperfections”, ensuring you never get bored.
