I've gotten my bass (MusicMan S.U.B. Series Stingray 4) and every time I go to a low note it sounds so horrible, the note is barely audible and sometimes now if I just pluck a string by itself it sounds bad, but when I'm playing a bit high it sound good. Anything higher than the fifth fret on any string is good, lower is bad. And I want to play lower!! I just don't know if its because I need new strings or if its my amp. My amp is a very small normal guitar amp that I got with a starter kit with my electric guitar and I heard that it can't take a bass's frequency. I haven't been playing for longer than half a year (I'm pretty good though) and I don't know every single thing about basses so please refrain from saying I'm stupid or anything, I'm just ignorant.
