The Skylark Guitars Pitch Pipe is one that I've had for quite a while now, in fact I've had it for as long as I can remember playing guitar. While it doesn't see too much use any more, it's still a good thing to have around. While I do have an electric tuner in the Boss TU-2 pedal, for tuning acoustic instruments that don't have a pick up, a pitch pipe can come in handy. Skylark's Pitch Pipe in particular is a good one as it gets the job done without any troubles. While I haven't ever encountered a problem with it, I also can't say that it stands out, but what type of pitch pipe is going to anyway? It basically does what it does. There isn't anything to using it as it simply has six pitches that you can blow into to tune to, and obviously since this is a guitar tuner, each of the six notes corresponds to the six strings found on a guitar. You'll find other pitch pipes for other instruments like mandolin and violin that just have four. The major down side to using a pitch pipe that it's really only good for the instrument that it's made for. The good news is that it's probably the cheapest way to tune your instrument save for tuning to something digital on the internet or on your phone, which I find myself doing more and more. Unless you have an acoustic guitar that you're going to be bringing around and that you'll need to tune on the fly, the Skylark Guitars Guitar Pitch Pipe is probably not going to be necessary for you, but if you do find that you need a pitch pipe, this one is as good as any out there that you will find.
