Zero Point SDX Removing The Direct Signal

[Ric046]

HI, I'm trying to figure out a way of modding my Zero Point SDX so I only have to delayed signal coming out. I'd preferably like to do this with a switch, so the pedal can be switched back to it's normal functionality whenever I prefer.

My grand idea is to send the pedal through the send/return of my amp and then included other FXs such as Reverb. Hence the reverb would only effect the delayed signal and not the direct signal.

Looking at the schematic I thinking throwing a switch in around the R4 region might do it but I'm really not sure of the implications of this. Also I'm not sure what effect this will have on the path switch. I'm guessing the pedal will stop working when 2 and 1 are connect.

I know pedals like the Boss DD3 can do it via a separate output, however it doesn't seem too common place among delays. Any help in figuring this one out would be greatly appreciated.

Cheers
Ric

The direct signal gets mixed in via R4.
Break the signal flow there to get rid of the dry signal.
Switch in R4 and you are back to stock.

There's virtually no interaction with the wet path.
