these are the two different ways i have found for making an a/b switch, the first i made from a looper diagram i butchered slightly (ie, getting rid of the return jack)

the second is the dod version just redrawn by me

so which would be the preferred version?

Go to fulltone.com, and look under "Tech Tips". Mike Fuller has a great diagram for a really good, simple A/B box which grounds the output of the channel not in use. FWIW, it's the same diagram Eric Johnson uses for the A/B boxes with which he channel-switches his amplifiers. I built a couple, and they work very well.
Hope that helps,
