4PDT to switch effects order?

I've been reading RG's take on this using cmos and relays and such. I have a rotary 4PDT switch and I wanted to experiment in changing the order of 2 effects. I know this can be done, and I've searched through the archives, but to no avail. Does anyone have a schem or diagram on how to do this?

Example:
Effect1 + Effect2 in one box. Sometimes, EFX1 sounds good before EFX2... sometimes the other way around. Instead of having patch cables, I just want to flip the switch and reverse the order. I would still have a stompswitch to activate the effects. Would this work? Am I making any sense? Should I just go and take a nap and stop chewing on solder? :?

Apparently you didn't make it to "The Juggler" which is just what  you're asking for.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

I did... but I'll go back and re-read it. :)

Ok, RG... I'm stuck. I threw together a quick diagram but I'm lost when it comes to the (IN) and where the wires go.



Help? :?

If anyone else can help, this is the original article that RG published...

OK, let's think.

The input switch section has to get the input wire on its middle/common terminal, and the two effects inputs have to connect to the outer lugs of that switch section, as well as to the other lugs for switching to the other effect.

It's easiest to do things like this if you (mentally) flip the switch one way, say down for example, so the center lugs across the switch are connected to the bottom lugs nearest them. Now hook up the wires and trace out whether the signals flow from ins to outs in the correct order.

Now flip the switch the other way, connecting all the centers to the top row lugs, and follow the wires to make the path ways work. I think you're only missing the two wires from the input section to the effect inputs.

Ok, I think I got it... am I close? :?



This would be really cool if I could get it to work... :D Thanks for your help, RG!
