I was going to change the strings on my guitar today with older string packs that I haven't completely used and a new pack. Since the low E, A, D, and G rarely break I have an excess supply of them and tried to use them instead of using all the new strings out of a new pack. I noticed that some of my older strings have already started to rust and threw them out immediately instead of putting them on my guitar. Is there a way I can store these excess strings so they can be used at a later date or should I just buy a new pack of strings every time I change my guitar strings?
I have strings which could be ten years old or more, not stored particularly well, and they are fine when they get put on, and seem to last as well as new ones. They are mostly Ernie Ball and Picato (others are available !) and stored in a conservatory which probably isn't completely dry. Put yours into a sealed plastic bag, with silica gel, that should solve the problem.A warm room ought to be a good place, too.
Because I use a strange mix of strings,as in I can't buy a set with exactly the right gauges for me, I tend to buy, for example, 10 of 008s, 10 of 010s, etc, so it's an idea for you. It's not necessary to buy a whole pack that may not all be used.Ask for a bit of discount for bulk buying !
