Since my childhood, I was very fond instrumental music, and I only got a chance to learn guitar when I was in my mid 30s. In the initial days I had faced problems tuning the strings and at times I used to struggle to tune the strings correctly. One of my musician friends suggested me to use a snark and he mentioned that I would be able tune any string without giving much stress to my ears.
Soon I got one, and I found it to be really useful. Firstly, I really like the small cute display with a digital equalizer of red bars moving from left to right when I pluck the string correctly, a blue bar appears on the screen which means the string is accurately tuned. I find it quite useful since I live amid a noisy neighbourhood and it is particularly very useful since it senses the vibration of the instrument and tunes up accurately in just a couple of minutes. I find it very nice and useful gadget for me and it can tune any instrument, which has strings on it like guitar or cello.
