Due to popular demand, we have added more to our listings. This is a contoured microphone for converting an acoustic guitar into an electric-acoustic guitar. Ideally, it should be installed in three places: on both sides of the back of the soundhole and near the bottom of the back of the soundhole❣️ You can easily attach it with the adhesive on the back of the microphone❣️ Basically, remove the strap end pin, widen the hole to fit the shield jack, and secure it tightly with the screw-type jack❣️ Attach the wires in a few places with the included adhesive sheets, and you're done‼️ Quantities are limited, so if you're interested, please order soon‼️ ※We also offer modifications to convert the acoustic guitars we sell into electric-acoustic guitars, so please inquire※
