Thanks, that's what I thought. Is the 'depth' wired "backwards" as well? I realize that depth/delay are not at all independent of one another and very interactive.
When you mention the feedback pot, what do you mean? In the build doc, feedback is listed as a control, but there isn't a feedback in the schematic? Did you mean the depth?
I actually wired up a feedback knob between the junction of pt2399 pins 11-14 and 15-16 (with a resistor and extra filtering cap) to add more repeats. A bit of a rudimentary integration of the feedback used in other pt2399 delays.
