Sorry, Sikes, I have no idea but I love the idea of it all. Singing into the spout. Genius! All the best with it and I hope you can share a video once it's done.

Bear :)

Thanks! This is something I've done MANY times. I wish my problem could be sorted with the youtubes...I've yet to find what I'm looking for.

treating the mic (3 wire) as a pickup (2 wire), use pins 1-ground and 2-positive from the mic, ignore the other one (3-negative)

I think your biggest problem with the mic will be feedback.

Okay I get it now, I thought it was inside the guitar instead of detachable from the guitar. My Bad, carry on.

If you're referring to Jack White's Shure Green Bullet mic, it actually winds up inside the guitar. There's footage of it in "It Might Get Loud" where he shows it being installed.

But there are commercial solutions for Adam's design. A belt pack clip-on lav mic, powered by a single 1.5 V AA battery, would be the easiest.

How about a Tin Can Mic like CBGitty sells wired through the guitar's controls? It could be hooked up to the can spout for an echo/reverb effect like a Talkbox.

If you intend to feed via the same jack as the guitar signal, you might need an impedance matching transformer in the gas can as well, i suspect like others that feedback might be the major obstacle though.

Acoustic/piezo preamp?

Adam,

I am trying to understand the question a little better. You have a mic that runs on DC voltage and you want to power it with a 9V battery? It is sort of like Phantom power and that is what you would want to emulate. Crazy old guitarists used to power onboard electronics with 3 wire cables to get the job done. With 3 wires you can combine the audio signal ground with the negative side of the battery signal on one wire. Positive audio signal on one wire and positive 9V on the other wire. So you want the mic audio coming out of the guitar amp?I'm sure this has been done both ways. What you want to do can be done, but it does need to be done right. The input of your guitar amp does not want to see 9VDC , but you can block that with a diode. Let me doodle a little with a wiring diagram. It sure sounds do-able.
