Passive AB switch

I have two basses that I use and would like to have both of them plugged into an AB switch that I can toggle between the two depending on which one I want to use. I can't seem to find one that doesn't need power. I don't have any other pedals and would like to not worry that a battery might go dead in the middle of a gig.Does any one know of a true passive AB switch?

I use a very small one from Loop-Master

Check the StuMac archives. They had a how to vid on making an A/B box. I found it after a guitarist I was playing with said he was looking for a way to have two guitars plugged in to his rig without having to plug and unplug. The SM vid detailed how to build a stomp box style switch using an old (IIRC) tuna can. I built several of them for various friends but it’s been too long ago to recall the specifics.

the problem with this idea is that it's easy to end up with two plugged-in instruments tangled into a big ol' knot by the end of the set

it's probably better to just mute with your stage tuner (you are using a stage tuner right?), unplug and switch

either way, most AB-boxes are indeed passive and will work with no power. trouble there is now you can't tell which instrument is on, leading to wasted time on stage. since the battery on an LED-equipped box would just be running the lights themselves it'll last a super-long time

For the last 7 years I've been using a Radial Bigshot I/O for instrument switching.
Passive signal path, provision for level matching (with switches to prevent treble loss - or bypass the whole circuit), an option to run power for LED indicator lights (which can be a good idea on a larger production IME) tough as nails and not too terribly expensive.
