I am having big problems with my geddy lee jazz bass neck. The d string and the a string have virtually no depth below the 8th fret. I have tried raising the saddles, changing strings etc. I am thinking of buying a new neck, one that isnt so thin, but first i would like to try to exhaust all avenues to try to fix the problem. I was wondering if any other TBers who have the geddy lee have problems like this with the neck... or any tips what to do about it.
