viva Analog "OPTO-Vibe" // Guitar Demo

My 2008 "OPTO-Vibe" is a design challenge aiming to replicate and extend the classic Univibe "Bulb-based" concept using completely different optical drive circuitry. The difference is that cell resistance varies over five decades of resistance variation instead of the customary three. Using four matched (fast) Silonex NSL32-SR3 opto-couplers also allows for higher speed operation. Overall, an extended Univibe circuit that replicates the classic feel of the famous circuit.
