I implemented a guitar stomp box circuit several years ago. It eliminates 50-60Hz hum for single-coil guitar pick-ups. I implemented and simulated this circuit in LTSpice. I then had a design shop convert the Spice circuit to Altium for fabrication and assembly. I recently had a prototype built from the Altium files. It does not work properly. It was not assembled at an assembly house; it wa...
