An electronic latching mod for the Tera Echo TE-2 pedal. Look, mum - no microcontrollers! All it takes is just three transistors, a few diodes and some passive components, none of that newfangled Arduino stuff. It's just a RS trigger, a base building block of the old school digital electronics. Built with diode-transistor logic, as seen in the Soemtron!
