just changed the strings today on my Ernie Ball Musicman Stingray and am having a huge problem with my D string. When stringing it up and tuning it is starts tuning up then seems to "slip" and drop tuning and wont really get any higher then B or C before it drops way out again. When i first strung it up i got it to D and it also seemed to develop a HUGE deadspot between the 14th and 16th fret on the D strings. I played a for a minute and then it went out of tune. I tried it again and the string actually came popped right out of the tuning peg!!! I dont want to play with and make it worse but i think it may be happening to the G string as well! Im probably going to have it looked at tomarow but I would possibly like to know what the problem is before bringing it in. Thanks a lot.
