hey guys, how are? here is my problem ... since i broke up with my girlfriend i have stopped playing (about two weeks ago). so today my birthday present arrived (Ed Friedland's Bass Improvisation book) and i picked up my axe again. as i started playing something felt wrong... really wrong... the action of my strings is almost two times as high as it was before. i changed the strings to a lower tension (from 45 to 40's) very recently and i haven't ajusted my truss-rod since. can this be the problem? or it is just because i haven't been playing in a while? ohh and by the way my bass is a Fender American Tradicional Jazz Bass '01 Thanks already!
