From the vendor

A dual-OTA analogue vibrato and chorus effect based on the runoffgroove Tri-Vibe design. Two cascaded LM13700 all-pass filter stages are swept by a triangle-wave LFO to produce smooth, pitch-shifting vibrato with a distinctive character. The SWIRL switch adds a second tonal character by changing the output mix. All circuit credit goes to runoffgroove.com . The Tri-Vibe is a faithful PCB implementation of their analogue vibrato design, adding a rate-indicator LED and polarity protection diode. You will find extensive sound samples and original documentation on the runoffgroove website. This PCB provides an easy-to-use layout for a great-sounding vibrato circuit. The standout feature is the SW
