2 channel tube screamer

[JohnForeman]

I'm sure this has been answered 100 times on here but a couple hours of searching and still haven't found what I'm looking for.  I want to modify my tonepad tubescreamer so that I can switch between 2 different vol/tone/gain pots.  Basically making it a 2 channel.  I would like to be able to do it with a single foot switch.  Does anyone have something showing me how this would be done?
Thanks in advance!

Thanks for the link.  Looks like I can add all three pots by using a 4pdt switch.
Thanks
