AD-9

[Synchrony Pedalworks]

This pedal reflects @blackhatboojum hard work with this PCB. It is a monster of a circuit, but a great, warm delay. I had some added clock noise, but placing a 22 pf capacitor across pin 1 and 2 of the 4558 IC cleaned it up nicely. I do not recall the reasoning, but it worked!

I built one of the blackhatboojum AD9 pcb's and love it. warm with a touch softer repeats than other analog delays I've built biased mine at 550ms.
