under the knife pt2

the second vivisection that i will be doing will be a guitar tuner. i chose this item because it run under the same kind of theme of sound and light. the guitar tuner has a head phone jack as well as an input jack to plug in your electric guitar as well as an output jack to plug into an amp. in addition to this the guitar tuner can also be used for acoustic guitar that don't have the option to plug in.

the guitar tuner also runs on a single 9 volt batter.
