how bad is it?
hey, so i bought slightly used pacifica 3 days ago as my first guitar and she came with a little rusty (i think its rust) strings, they are only rusted there not spreading right now. Should i replace them, or not worry too much and just practice on them? i have brand new d addario 9-42 in my drawer, just dont know if i should do it now, thanks for advices!
