I lost my old guitar tuner.So I ordered a new one ( ENO ET-30 clip guitar tuner ) from Ebay few weeks ago and I received it today.It's very handy.You might think why someone need a guitar tuner if he can tune his guitar by ear.Don't be scared to use a guitar tuner.It won't destroy your talent ,if you use it wisely.Ear can't help in some situations,For an instance : In a noisy background just before a concert starts.You can't hear your guitar and you are anxious.You can't tune your guitar properly.Guitar tuner will help in those situations to tune your guitar accurately although you are disturbed.
Here is my new guitar tuner.It can be clipped to the guitar.It becomes green when correct pitch is achieved.
