I'm sorry. What I meant was that being a beginner,after someone tunes your guitar,keep your "your tuning gears.you know those six little knobs that the strings are attached to ie. Grover Kluson etc. from accidentally being turned or the guitar will go out of tune. Actually after you've played for a number of years, you dont really need a tuner, just a root note from any source like a synth or harp etc. The rest can be done by ear......that is after your ear gets used to the different beats of the tones, and after you've learned that a guitar is tuned in "egual temperment" meaning that there is no such thing as a perfectly tuned guitar. but that is a whole different ball of wax.. I should have said tuning Gears...I didn't mean Guitar tuners...All beginners need em...All the best...
