How can I use the Guitar Mic with a guitar amp or stomp box?
Plug a phantom power supply between the mic and the amp or stomp box. The ART Phantom I and Behringer PS400 work well and cost about $40. Connect the mic’s XLR connector to the phantom supply input. Connect an XLR mic cable between the phantom power supply output and a Radio Shack A3F XLR jack-to-1/4″ plug adapter/transformer, part no. 274-016. Plug the Radio Shack adapter into your guitar amp. You can use any other female-XLR-to-1/4″-plug adapter transformer, just be sure that it has an impedance matching transformer (also called low-Z to high-Z transformer).
