"Up, Down, Daddy!" PCB
My daughter melts my heart when she asks me to "Up, Down, Daddy!" when throwing her up into the air and catching her. I figured this was a perfect name for an octaver with 1 octave up and 1 and/or two octaves down.
- Difficulty
- Fiendish
- Based on
- Pearl OC-07 Octaver
- Smallest enclosure
- 1590B
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.
