The Boing! is a Light Dependent Resistor-controlled low pass filter. It takes its primary inspiration from existing ultra-simple yet delightful passive Vactrol LPG modules such as the PassiVac and DPLPG, but adds JFET transistor input and output stages and an active LED control circuit, thus enabling the introduction of wonderful Feedback and Trigger functions, LED brightness offset, and a second filter stage. Combined, these features allow for incredible variable-cutoff overdrive and low pass filter sounds in addition to bouncy LPG Bongos and more.

This kit has all smd parts already pre-soldered!
