I became interested in this effect after hearing a demo clip of the Pearl OC-07. After a bit more research, I realized that gaussmarkov had created a schematic for us. The only catch was: I didn’t want it in a 1590BB. I wanted to see if we could put it in a 1590B.
Well, it’s complicated, and it sure looks like perfboard, and it’s a tight fit, but it is possible to fit this in a 1590B.
Take your time. It’s not an easy build. It worked for me the first time, thankfully! However, it’s double-sided, and parts are “intermingled.” So plan it out.
