Bazz Fuzz capacitor switching

[Widows]

Hi all,

I've just got done building my first Beavis Board (http://beavisaudio.com/bboard/index.htm), it's a bit ghetto as it's very much a first attempt that I'll be revising at some point but it works great. I built it so I could prototype different designs before boxing them up and putting them on my pedal board. The first project I tried out on it was the Bazz Fuss (http://beavisaudio.com/bboard/projects/bbp_BazzFuss.pdf):

I've modded it a little bit using a different diode (1N4001) and changing the input capacitor (C1) with numerous different values and voltage ratings and got it sounding really beefy, but I would like to be able to install a switch into the breadboard layout to allow me to A/B between two different capacitor values to see how the sound is altered by each one. Can anyone please advise me on how I would do this with the layout shown in the Bazz Fuss link above?

Thanks

PS: Apologies of there is already a post like this up on the borad, I had a quick scout about and didn't find one so I started my own. If there is already an answered post like this one then please direct me to it and I'll take this one down

Probably the easiest way to go about this is
1) Soldering one wire to each lug of a DPDT toggle switch. The caps are polarized (orientation matters), so it would be a good idea to use different colors. You will have a total of six wires;
2) The wires connected to the middle lugs will go to where the cap leads would be (on the Beavis layout, the positive of the input cap is hole c2, and its corresponding negative is c7);
3) The wires connected to the outer lugs will go to empty spots on the breadboard. Something like f2/f7 for the lugs on one side and f8/f13 for the ones on the other will do;
4) Put one of the caps you want to test into g2/g7 (or h, or i, or j) and the other into g8/g13.

That should do it. In case I haven't made myself clear (I guess I can take that for granted...), the switch will be connected like this:
    _______________
    |                          |
    |   F2        F7       |
    |                          |
    |                          |
    |    C2       C7      |
    |                          |
    |                          |
    |    F8       F13     |
    |_____________|

Hope the tentative diagram made more sense.

Edit: sorry, that's not the easiest way. The easiest way is just yanking the cap out and inserting the next. It's a breadboard, after all.

The easiest way is to have the smallest value cap wired in as usual, then take a wire from each side of the small cap.  One side goes to a SPST switch, the other to another cap then to the switch. That way switching the switch on gives the 2 cap values added together as they are in parallel.
