Anyone know if I can use a 1/4 inch jack socket such as thus -

To control the battery on a ruby amp as it does with active pickups?

Time on earth is like butterscotch; you really want more, even though it will probably just make you ill.

so you want it to only be on when there is a guitar plugged in to it right? that should be really easy and would just use a standard stereo 1/4" jack. lots of information on how to do this all over the place, shouldnt be hard to find.
Ok, so as far as I know the Ruby has the negative terminal of the battery going to ground right?
I'll try make a quick diagram for you.

Edit: found this
I'd wait for some confirmation from some other users before trying this though, just in case, because I haven't.

yeah you can. that's what I'm doing on my mini amp. You just solder the (-) of the battery clip to the extra lug.
