When ever I break a string, which happens occasionally, I grab one out of another full set I have. And now over the years I've accumulated quite a few sets that are missing one or two strings. It's mostly the high E but the B and G are also missing out of some sets. I have plenty of Low E, A and D strings so it seems wound strings aren't the issue. And I can buy single strings from a local music store but they want like $1.50 each for the E and the price goes up the thicker gauge. So I was just wondering where do y'all buy your single strat strings from?
