hey. i don't know if this is a stupid question or not. so i recently bought my second bass, i've been playing for about 4 years. i don't know any theory really or anything about the instrument except that i play tabs and i play them well, although alot of the stuff i play isn't that complicated. anyways, i'm off on a tangent. my new bass has 3 knobs, my old one did as well, and i was wondering exactly waht they do. and if there is a standard this does this. or anything. there are 2 pick ups on the bass. the guy at the store explained it but i didn't really catch on. is the first one. (the one on hte right if you are looking towards the bass in front of you) volume, then the pickup closest to the neck, and then the other pick up. is it possible to know what pick up is waht. what do i do for different sounds. do i just have to screw around with it? sry this was so long, any help at all is appreciated.
