The 1590B enclosures from Small Bear are slightly roomier on the inside than the ones from Tayda (because of the thinner walls). So, the 2.2" wide board just fits. Plus, this is a really cool blue color. The knobs are from Small Bear too. I meant to take a pic of the solder side of the board to show how the pots are oriented, but I forgot. The Rate and Depth pots are rotated 180deg from how they would normally be mounted so that they are inside the perimeter of the board instead of hanging outside the perimeter like the board is designed. I had to use solder lugs and short wires to reverse lugs 1 and 3 in an 'X' shape for both pots. The Feedback pot also uses solder lugs and wire to move it over to the side.
For the blend knob, I just put a simple BJT buffer on the dry side and a 50kB blend pot. You can kind of see the buffer vero board, which is superglued to some doublesided tape down next to the footswitch. I experimented with a buffer on the wet side (before the phase circuit), since the input impedance is only about 390k(?), but it didn't seem to make a noticeable difference.
I set the trimmers by ear, but ended up similar to what some others have suggested, the 10k trimmer at noon, and the 1k trimmer (sets the led brightness) slightly high at about 1:30. With the brightness trimmer lower, you get some wonky glub glub sounds at high depth settings, and bringing the brightness up smooths it out.
I don't have much experience playing with phasors, but I really love the sound. I think the blend knob is really nice, allows some textures I can't get just by changing the depth and feedback knobs. Hopefully there's a blend pcb available on here soon so it's easier for people to access this mod.
