well i just got a new amp with a built in tuner yesterday and one of my basses was way outa tune, i got it so the green light came up, well about 5 mins later i looked up and it was flashing in the red, well i tested it and all 4 strings were out of tune equally. i know when a bass wont keep its tuning it usualy means the strings are wore out which they mite be since it came with the bass from a pawn shop. but since they went out of tune so fast and its a really old bass could there something more serious wrong?
