Re: Can I do this with a uProcessor?


">
I assume the 9V powers the effects pedals. What are the 5 and 12V
currently
doing ?


5v is for logic, and 12v is for relays.

How would you wire the JFETs so that they could work as bypasses for the
effects without grounding the entire chain?

I don't understand the question I'm afraid. Can you rephrase it ?


Well, right now the relays are hooked up with the inputs paralleled:



FX1 FX2 FX3 FX4

I've drawn a couple things with JFETs, but I'm not sure how to get a similar
setup using JFETs instead of relays.

Thanks
