Hi, I use 10 guage strings either Ernie Ball or D'Addario. Last week I purchased 2 sets and it's 9.5 guage D'Addario. Even though I bought it, I am not able to convince myself to use it, so I am thinking of trading with 10 guage strings if anyone might have it and wants to dispose. The strings are brand new in the pack and just 4 days old. I am game to exchange it for a good quality 10 guage strings of any company. The issue is 10 guage is not available in Bangalore easily 'cos hardly anybody uses it.
