I play in my church band and I bought this to amplify my acoustic guitar (rather than using a mic). This product works great and is a good price. It easily can be inserted and removed from the sound hole but STAYS in the sound hole while you're playing. At the same time it does not damage the guitar at all because of it's foam siding. This is definitely an upgrade from using a mic for your guitar, it gives you more freedom of movement, and a clear, well balanced output. I haven't had any feedback problems when using this pickup even when I have several musicians and monitors around me. The female end is awesome because you fit it right on your strap button so it's out of your way, and you can use any length of cable to plug into it.
