I just ordered a big variety of strings from an online vendor. They're a small outfit in NC, and sent a little note in the package about not cutting round core strings until after you're all strung up. That, dear comrades, is a hard thing to do with a "safety tuner", like Fender mostly uses. What happened to the old ways.... when Fender themselves used to tell you to BEND the string in at least a 90 degree sharp bend, to prevent the windings from coming loose from the core? I guess good ol' Fender 150's are not round core any longer, so it doesn't apply. The other thing this vendor mentioned was to use strings within 3 months to prevent tarnishing and rust within the packaging (without ever being opened). I gotta say, back in the 1970s we just stuck the BOX of strings in the deep freeze to prevent just that. Anyway... just a thought for today as I sort out my big string order..... Trying gauges, and brands to see what's good n not-so-good.
