Circulator Build

Here's my build of a Circulator. I built a Phasor 2 a while back and thought it would be fun to make this one, with LM13700's. These chips were hard to find at first - I could only find smd versions and I was pricing out adapter plates, and then I saw they are in stock at PPCB!

Here's the gut shot

And the front. Orange because it's a phaser.

This one has a resonance control, like a flanger. I like that there is a switch to turn the phaser into a vibrato - that's a nice added function. The rate range throttle is interesting - I had it in the middle position when I first plugged the pedal in and thought I'd messed up the build as it wasn't phasing - it turns out the middle position turns off the LFO.

I get bored of phasers easily, but this one has a few extra features so maybe it'll stay on my board for a while
 
GOATed circuit for sure! Definitely recommend checking out the Boneyard Mods for it if you ever make another, they're intricate but beyond worthwhile if you wanna maximize the trippy.
