Truly Speaking,I am not a guitarist and i don't even know how to play it with strings.But i love Music and i love to listen to Heavy metal and nu metal bands which uses electric guitars,rhythm guitars.But sometimes i've noticed that guitar tuners remain out of battery,that leads to play completely out of tune.Then after searching on internet for 2 days,i found a very effective guitar tuner software that can help you in tuning your guitar.
