Delay pedal (prototype)


Yes, I occasionally design and build pedals other than boosters or distortions!    

This is a prototype digital delay using an HT8955 chip and an jfet audio path to get more of a warm analog sound. As I remember, it has about 800ms of delay.

There are two of these pedals completed… I have one and Robert Keeley has the other. There are several more in various stages of construction around my lab…

I want to build my own delay pedal. I work at Radio Shack and have access to many parts so now I have the bug to build my own pedals. Any diagrams you can share would be great but I need to learn to read them.
