I built the Deep Blue Delay using Mark's layout (4 knob version) and it sounds great. I decided to add the modulation daughterboard but I'm having some problems...
In the modulation thread (here) several folks seem to have the same problem, but I don't see a solution.
The 3-way modulation switch is supposed to yield modulation / delay / modulated delay. I get the modulation, I get the delay, but the third position doesn't have modulation on the repeats - just dry delay, same as position 2.
While troubleshooting, I tried disconnecting the wire running from the main DBD board to the Delay 1 lug. That gets me modulated delay in position 3, but just dry signal (no delay) in positions 1 and 2.
I feel like I'm close - I'm just missing something. Any ideas?
