DOD 515 Sustain
I've never actually see this pedal, but I came across the schematic and I was intrigued by it.
There's the CA3094 OTA, often seen in EH pedals, but not so much by the other companies. This is comparable to a CA3080 OTA with a darlington output buffer (serves as a current to voltage converter), also comparable to a single version of the dual LM13600 OTA.
Then there's the very interesting TR10/11 darlington with shunt feedback diodes distortion amp, not unlike a Big Muff clipping stage.
TR7 starts a full wave ac to dc conversion.
Bypass footswitch is a CD4007 FET array design.
Regulated power supply built around J111 and TR2 is pretty impressive too.
TL062 gets used for input and output buffering duties. The 062 is a low current version. These were popular in the '80s but faded from use. Rare to see them now, IME.
