Description

DIY Transducer guitar pickup for vibrating guitar strings infinitely, sort of like the fernandes sustainer system but very lowcost off the shelf methods. Based on Evan Kale's concept but improved upon with PCB integration.
This is part of a larger project of building a special stringed drone instrument.

Details

Piezo buzzers with the tops cutoff and diaphragm arranged in an array, powered by an opamp fed by the guitar's signal or any signal you want to plug into it..............................
