Manufacturer’s description:

The Acoustic Tube SA-1 is a passive, hum-cancelling stack with flexible mounts that simply pop into the soundhole of your guitar. Its built-in volume knob is easy to access, which puts instant control of your signal level right at your fingertips. It provides crisp high-end detail, and a backed off midrange that gives it a smooth overall response. Great for all standard types of steel string acoustic guitars.The Acoustic Tube fits soundholes with a diameter between 3.85 and 4.10. It is very feedback resistant, and includes a short cable with a female 14″ output jack that you can connect to your favorite amp, PA, direct box, or console with a standard guitar cable. If you already have a jack installed in your guitar, you can solder this to your current jack. But if your guitar is currently totally acoustic, and you want to keep it that way, then you simply drap the cable on the outside of your guitar, looping it over the existing end pin, then plugging any standard guitar cable into the output jacket provided. This way you can enjoy an electric session one day, and remove the next to enjoy your guitar au natural the next. NOTE this is a magnetic pickup, and will not work with nylon stringed instruments.
