SolarGravity / Analog Vactrol-Based VCA - Eurorack Module - 4hp sequential_switch the remaining two can be

the remaining two can be used as input/output in either direction

All the way to the right is fully open

Cord is 6ft

Great for saving space in guitar petal setups or decreasing the output of hot instruments such as theremins/analog synthesizers

each VCA contains a DIY optocoupler

SolarGravity / Analog Vactrol-Based VCA - Eurorack Module - 4hp sequential_switch the remaining two can beThe Solar Gravity is an analog vactrol based VCA designed to bring the lovely response of optocouplers into the realm of clean, performance based Eurorack VCAs. Starting with this simple concept, the Solar Gravity utilizes some neat active circuitry to significantly reduce the bleed inherent in vactrol based VCAs and to provide the user with lots of control over the level, direction, and response of incoming control voltage. Though its primarily
