Without adding electronics, it would just be connecting the pickup coil between Tip and Ring, and the shield tied to Sleeve.
I will need to dig in my archives to find a phantom powered amplifier circuit. Unfortunately the majority of published phantom powered microphone amplifiers are for electret mic cartridges. I know that some dynamic mics have amplifiers internally but I don't recall seeing that circuit type published. What could work is to take the PCB out of a dynamic mic that has some damage. OR maybe a microphone company would sell the PCB. If it works for a magnetic mic it should work for a coil type pickup.

 

Post #17 says that the mic is an internal condenser mic powered from 5V to 9V but of course it is a condenser electret mic with a Jfet impedance converter that is powered from the low DC voltage. The acoustic guitar is hollow and does not have a magnetic electric guitar pickup.

Certainly correct, AG, I was thinking about MY Stratocaster guitar. So a circuit for en electret mic IS what the TS requires. If the present amplifier does not draw more than 7 or 10 milliamps then a phantom power connection should work, except for needing to drive the two sides of the circuit out of phase and with similar source impedance.

 

I have never looked at the phantom powering and balancIng circuit inside a PRO microphone. I have an Audio-Technica mic that has those features and I simply plug its XLR connector into a mic preamp/mixer and use it.

The beauty of Phantom Power is just that: Plug in the microphone and the power is connected!
There are circuits available for download in the "Schematics for free"website, about 4 menu levels in. But all you get is the circuit with the parts identified.
Probably other electret mic circuits are available somewhere else as well.
