DETAILED DESCRIPTION
Explanation: I am using a Yamaha Mixing Console MG12XU and I am a bass guitar player.
This Mixing Console do not provide a hi Z input for instrument but provides
Mic input with 48V phantom power supply.
The idea of this project is to design a small high impedance amplifier powered by the
phantom supply. This small circuit might be implemented into a Neutrik XLR adapter
like NA3MJ 3 pole XLR male to stereo 1/4" locking jack (Tip, Ring, Sleeve contact)
or NA3FM 3 pole XLR male - 3 pole XLR female (extention adapter).
Other possibility is to install the circuit into the guitar and use a XLR balanced line
from the guitar to the Mixing Console. Then no need of battery into the guitar.
Electronic tone control could be included in the guitar
