Use a DIODE to SWITCH AUDIO just like a TRUE BYPASS? Active Diode Switch Explained Part 2.

This video continues my exploration of active diode switching, but this time the simple switch from the previous video has been expanded into a full true-bypass replacement. Instead of using a mechanical footswitch, this updated circuit actively routes the guitar signal either straight through or through an effects send/return loop depending on user control... just like a modern pedal bypass system. After demonstrating how the circuit handles input, output, and effect routing, I test the design with two different power-supply configurations: +9 V to Ground (Single-Ended Supply) - In this mode the circuit works, but the noise floor is extremely high, making it unusable for most pedalboard applications. +9 V to –9 V (Bipolar Dual-Rail Supply) - With a full ±9 V supply, the exact same circuit becomes much quieter, gains headroom, and performs far more like a proper studio-quality bypass system. Along the way, I show the signal paths, discuss the electrical behavior behind the noise difference, and demonstrate the audible results so you can hear the improvement for yourself. Whether you’re building DIY pedals, modding stompboxes, or just chasing unique guitar tones, this video gives a practical, no-BS evaluation that helps you decide whether diode bypass is right for your setup. 👉 Don’t forget to subscribe to    / @madscientistguitarlab   for more tone experiments, pedal mods, and electronics deep-dives.
