Hi, did anyone build this one? I etched a board and everything worked out except I can only get one repeat out of it. Is there a "go to" error with BB delays when that happens or could it be just about anything?
Mix and Delay pots working properly but feedback does nothing, really.

One more thing, don't know if it is related. When biasing the delay I couldn't get it beyond usless. With both the pot and trimmer maxed=no whine.
