Great Flanger! I need to do some comparison to the MXR 117 flanger that I built a while ago. This is a fun build, but I wanted to share some issues that I experienced. Page #3 has the values of the parts listed, but there was one discrepancy. R20 is listed as 100R, but is 470R on the BOM and mock-up picture on page #14. I used 470R. I also did not have a 22pF cap, so I had to use two caps in series (27pF and 120pF). I had 33uV caps, but they were only rated for 16V. I looked at the schematic and realized that I only needed caps rated for 16V because I am using the V3207 IC. When noticing this fact, I realized that I didn’t need the voltage regulator (78L15). . My rate knob also did not work. I reflowed the joints and it is working. I hope it isn’t a bad pot. I don’t like replacing pots!
Well, I hope my musings will help someone else’s build!
