Switching for stereo dual overdrive

[stevewire]

Hello.
If anybody could send me in the right direction.  I have a friend that has a couple of guitars wired up stereo (neck/bridge pickups) and he uses two combo amps.   He asked me if I could build him a stereo dual overdrive pedal. 

I'm trying to wrap my head around some type of true bypass wiring for this.  Subtracting the use of an LED, could a 4PDT work for this?  And if so, could someone explain it to me?  I am sure you could do this with sometype of relay circuit, but I am so how looking for a simple yet elegant solution.  I've done lots of google searches, but yet I may not have been wording the search criteria very well.

The jist of what I am hearing from my friend and what he would like are two seperate overdrive circuits in the same enclosure, triggered simultaniously with a single stomp switch with stereo in and out.

Any help or advice is appreciated.

You could do it with a 4PDT and also get LED's, if you used the Millenium Bypass thing. I'm not entirely up on that, Juansolo used it a lot.

IIRC, the Molten Voltage clickless units will allow you to operate more than one relay off of one soft switch.

Check the pdf I've attached, I think this is what you mean. No Led though, would need a 5PDT for that.... I'd imagine this kind of thing would have a lot of possibilities for some very cool sounds! Thinking about delays and modulation in stereo right now!

one option that makes a 3pdt viable is modding a circuit like The Opto-Tron to switch two circuits.

You can use optical drivers and a 3PDT switch to get stereo bypass and an LED.

Thank you guys.  Definitely some options here on how to make this work.

Thank you Dutch.  Whether I use a 4PDT here or not, I'm bound to use that information at some point.

The optical driver stuff looks interesting.  I looked over the schematic for the Opto-Tron.  I don't think I am grasping how it works or how I could mod the idea to make it work for this project.  Any advice or direction on what I could read or use as a reference to get a better understanding?

I'll PM you. I can give you more info more easily there.
