Hi, I am a newbie at guitar playing. I recently borrowed a guitar (Givsons) from one of my friends and was learning how to play using a software called "guitar method". This guitar which my friend was using had not been played for a long time and so needed a little tuning. So, I was tuning the guitar with the help of my computer using a software called 4pockets guitar tuner, when I accidentally broke the first string, the "E" string. So, can anyone tell me what I need to do replace the string? Do I need to replace all the strings or just the broken one? Also I saw some guitar strings available on furtadosonline.com I was very confused as to what kind of strings to buy for this acoustic guitar as there are many strings with lots of different specs, eg: Granada, Acoustic Guitar String Set, .010, LGS 10/47. I don't know what .010 and LGS stand for. So could someone please guide me as to how I need to go about buying a new set of strings? I am planning to visit the furtado's store in mumbai. Also what is the cheapest tuner available in the market? What's it's cost and are they really effective or is it better to use the tuner on my comp?
