Would it be possible to make a pedal that switches the signal chain

[iamapirate]

When you plug an overdrive in before a wah, it gives a completely different tone to plugging in the wah before the overdrive. So I was wondering if it was possible to make a true-bypass-non-eletrical-without-a-chip-board pedal that when you hit it, it changes the signal chain from one to the other. Something like this would be cool but I don't have any circuit diagrams.

I think there might be a schematic for one at the Beavis Audio site...

Yes the Wobo Inverter delivers exactly what you need - passive operation, easy to use, just what you're looking for!

Their site says it uses relays and requires quite a lot of current. Not so passive, maybe.

A relay is just a "powered switch". Relays can be setup to switch over as many contacts as you want with one press of a footswitch. This can be relay useful (hah - did you see what I did there ? )

The current is used purely to operate the relay and is completely isolated from the signal side of the pedal. A relay-operated switch is more likely to be genuine "true bypass" than a normal mechanical switch.

The power is also used to operated LEDs so that you always tell which way the switch is currently set - this is very useful on a dark stage when you can't remember which way the unit i switched.

If you're interested I could build you one, I built the same thing last year for another guitarist to do just this thing. I think I've got enough parts around me to do it.

Well I meant no active electronics in the signal chain...

How much would that cost me? Ideally I'd like to make it myself, but I don't have the circuit diagram

[umph]

i just drew up a diagram for this and i uploaded it to photobucket but this site wont let me link to that. whats a good site to upload it to?

[Finbar]

I usually use tinypic?

[umph]

i hope this makes sense my paint skills aren't the best

[iamapirate]

haha ty!!!

EDIT

Thanks for all the help. I'm going to try out the one on the beavis audio site (http://www.beavisaudio.com/techpages/PedalHacker/OrderSwitcher.gif) as it looks like the easiest to do (no offense at all to paint )

Thanks again for the help

Could do it for say £30, just to get the parts used up I have spare on my workbench.

EDIT - just seen that you're building one, but if you don't go through with it I can do you one in a few days.

no worries its the same layout except you can actually follow that one haha.
