I thought I knew how to do this, but for some reason, this latest installation isn't working. When I attach the momentary switch, it has the reverse effect, turning the guitar on when depressed instead of turning it off. I reversed the wires and the same thing happens. Any ideas? I'm installing this on an old Kramer Barretta with a Sustainer; not sure if that has something to do with it. Thanks.
Okay, I guess I'll explain that a little more. The reason that ijustwannastrat wants you to use the right side circuit is because he has correctly deduced that you have a "normally open" or "momentary on" switch.
The two main reasons for the right side circuit being used more often:
• It uses the much more common momentary "on" switch. Heck if you wanted, you could use a doorbell switch for that. Yes, it would look ugly but it would work.
• That circuit actually shorts the output which produces a much cleaner cut off rather than just shutting something off.
We don't actually know how axekicker has the thing wired. Considering that we've helped him with kill switches before, I'd almost bet that he has got it wired per that right hand diagram, but has a normally closed switch.
When wolf says "cleaner cut off" I think he's referring to noise. The left hand method leaves the hot lead of the cable hanging there like a big antenna straight to the amplifier, and could get nasty pretty fast. It might not be a big deal for quick stuttering type things, until you're trying to do it in a bar with neon lights everywhere.

I think ashcalt is correct. I've done a bunch of these installations. Usually to the middle post on the volume pot and to ground. I think I was sent the wrong type of switch. I also tried attaching to the jack and no dice there either. Thanks guys.
axekicker Yes, you could just put the meter leads directly on the switch terminals. If the switch conducts and then stops conducting when you press it, you have a momentary off switch and you can hook it up by using the left side of that circuit diagram.
