Forgive me if this is painfully obvious or stupid on my part ![Embarrassed :-[](https://www.madbeanpedals.com/forum/Smileys/default/embarrassed.gif)
After reading quite a few recommendations from different pedal builders, I ordered one pound of Kester 245 63/37 solder from Amazon. I got it today and the manufacture date is from way back in 1992. The Kester site says the product has a shelf life of three years. Should I be concerned about this? The interweb seems to say that the flux goes bad...
I know I should just try it out and see for myself, but I'd hate to use it and then not be able to return it on account of it being used. I'd appreciate any advice you could give.
