 It just feels like an acoustic guitar, which was kind of the feeling that I wanted to provide. So that feeling where you can just pick up and start playing. It's already kind of a part of your instrument. If you're in a jam, if you're outside, you don't have to worry about where it is. And it's really fun. Now, some of our customers don't attach it, and some of them only attach it and everything in between. So it's one of their unique features, but it's certainly something that you have to do. It's also wireless, right?
