I built a Deep Blue Delay and added a modulation board. The modulation is wired to a 3-way switch (half of a DPDT on/off/on) and should yield the following:
(1) up: modulation only
(2) middle: delay only
(3) down: modulated delay
Positions 1 and 2 work great, but I'm not getting any modulated delay in position 3 - just normal delay (same as position 2).
Here's a crude drawing showing the two boards and my switch wiring:

If I disconnect lug 1 from the main delay board, I get modulated delay in position 3, but nothing (dry clean signal) in positions 1 and 2.
How can I wire the switch so that lug 1 is connected to the main board in positions 1 and 2, but disconnected in position 3?
Any other suggestions are welcome. Thanks in advance.
