  • Digitech PDS 8000 Echo Plus 2 and 1/2 second issue

    The pedal works perfectly in 8 second mode. However, when I switch to 2 or 1/2, the effect doesn't work. When it kicks in, it basically doubles the signal overtop of the input, i.e. Just makes the sound a little warmer. There are no trails, echos, or repeats. The delay controls don't seem to change anything. The controls all work perfectly in 8 second mode however. I've recapped and swapped ICs. I get the voltages on the 4066 when sliding the selector switch. Interestingly, if I jump pins 3&4 (I originally thought it was the input/output, but according to the schematic it's the input/output of the 8 second delay path), the effect kind of works with proper delay time. When I have it on 2 second and jump it, I get a noisy 2 second delay. If I slide to 1/2, same deal. The infinite delay doesn't affect 2 or 1/2 second stages when engaged either.
