hi i have a fender jazz bass and in the beginning i changed the string heights to get rid of some buzz and now i think that it was a bad idea cuz for a while my e was dead as crap, but now i got it sounding like i want but the other 3 are to bright and twangy for my taste but im kinda scared to mess with it again and a explanation of how string height effects sound would be nice cuz im confused and and other tips on how to mellow down my a,d, and g would be awesome thanks
