Hi ya, I've got a Sabine stick-on tuner and I'm really happy with it. They say you have to move it to a slightly different location on the guitar every so often, as there's a chance it will mar the finish if left in one place for too long. I'm not worried about that myself, since my guitar is made of masonite and slathered in a thick coat of paint, but take heed if you're guitar has a laquer or poly finish (which most do). The Intellitouch are good as well, and I think they must have improved the design within the last couple of years, because the first time I tried one three or four years ago, it didn't work at all, but I've borrowed a couple since and they've worked fine. Anyway, hope that helps. Timothy
