Arduino Guitar Delay Pedal

An attempt at an Arduino guitar pedal. The guitar signal feeds through a PT2399 delay circuit, modified to include a JFET preamp phase. The delay circuit has Echo and Delay knobs. From there, it feeds into an optoisolated-Arduino-5V preamp, and out to the Arduino. The output from the Arduino is filtered and sent to the amp.
