Piezo-Electric Spliter box

[chad1655]

I have a attached a photo of an item I would like to know how to produce. I have two (or more guitars) I play through at any given gig. The "A" input would be for a standard guitar and when engaged would always go to the main (mono output). The "B" channel input would be a stereo jack (electric guitar with a piezo bridge pickup). When this channel is engaged I would like to be able to select between tip, ring, or both. I would also like a tuner mute to be included so I can tune either guitar. I would assume this combination is similar to a regular A/B box and a stereo splitter box. Any help would be greatly appreciated.

You do not specify which signal the tuner should hear. (Since it's the same strings, I assume it matters little, and TIP is more likely to be live on all guitars.)

The unused poles on switches can be used for LEDs.

EDIT: I got tip and ring switched somewhere. Trace it out and satisfy yourself that you got it right.

Thanks. I'll try it this week. I see what you mean by tip/ring switched. But are those 3pdt or dpdt on the outputs?

Only need to be 2P2T.

If 3P2T are cheaper by the dozen, use them, ignore the extra bits.

It's pretty much industry standard to use the tip for the magnetic pickups and the ring for the piezo pickups. If you have a guitar that uses a Fishman PowerChip or similar active circuit it will also know if you've plugged a stereo cable into the output jack and will split the signals or if you've plugged in a mono cable in which case the two signals will be summed together.
