This thing has some interesting sounds. I did a few minor mods. I bridged pins 1 and 8 on the 386 (underside of the pcb) so it would be at minimum gain. I also used a 386-1 for less gain. And then I used a TL072 in place of the 4558.

It stays fairly clean when I’m on single coils. You can get typical modulated delay sounds with this. You can also get really extreme pitch swings on the repeats. Very fun when exploring self-oscillation. The blend knob could use some improvement.
