Fun with Electro-Harmonix

Heavily modified my Frequency Analyzer to utilize a single installed jack to function as either an expression pedal input(without expression pedal in the FA is just as normal) or a Carrier In depending on the position of a switch.  The Carrier needs to be a line level, so I needed a boost circuit built into the pedal, so there’s a dial to control the amount of boost if needed from an instrument input.

So low and behold, the Frequency Analyzer with Selectable Expression Pedal or CV Input jack, toggle and pad to accommodate various CV input levels and automatic link of Input signal to Carrier.  With LED.
