Acoustic guitar tuner
A guitar which is out of tune sounds horrible. Although it might be easy to tune the guitar yourself, this is a little more complicated if you are on a stage. The audience will get noisy when you tune your guitar between the songs. For this reason, a guitar tuner is very useful.

If you are playing an acoustic guitar, you don't have to have something like an acoustic guitar tuner. If you are using the line-in of the tuner, you only have to make sure the sound isn't clipping. It won't break down because of the signal of an acoustic guitar being stronger than that of an electric one.

In general, four types of guitar tuners are available. Clip-on tuners are placed at the guitar's headstock, and it measures the vibration frequency. Another type of tuner is the 'normal' one; a box which is a few inches in width, which inludes a line-in and a mic. They are cheap and versatile. The third category are the floor tuners. They don't have a mic, and lie on the floor of the stage. Mostly they do have a mute pedal. The most extensive tuners are the racktuners. They can be placed in a 19 inch rack, have a large screen and the expensive ones are very accurately.
