Hi, new to this forum and this is my first post. Any kind of help is appreciated.. I have a 99' rickenbacker 4003 and until now I have been adjusting the truss rods by myself when it was needed thanks to some web sources like joey's bass notes. However this time I have a problem that I think I am not able to solve by myself. There is something like a small 'bump' between 5th and 7th frets under E string, that causes problems while I am playing on e and a strings. There is no problem G side of the neck tough. However I am not able to lower strings they seem so high now. The main problem is that I don't know any luthier here in Istanbul that I can trust enough to leave my guitar. So far, I tried to changed the strings with lighter ones, I don't know if it was the right action to be taken, but I had Rotosound strings with I guess the gauge of .110 on E, now I have d'addario cb80 that has a gauge of .095 in order to reduce the tension on the neck, which didn't solve the problem, then I completely loosened all the strings and both truss rods, waited around two days, but still that bump, that ''S''shape was there on the E side. So now considering that I don't have access to a rickenbacker master luthier, I'd really appreciate your comments about solving this problem, if I can do it by myself! Thanks a lot!
