Hey, Im a Guitarist/Drummer who owns a Bass for recording and versatility...i really dont know much about it other then how to play it at a poor level. I have an 85' MIM Jazz Bass and a Crate 100 watt amp w/ 15" speaker. Heres my situation. I love Deep, Low bass. And this Jazz Bass doesnt do a very good job at that, to me. It maybe something im doing, idk. I just need help. Im looking at buying a bass with a Neck-Thru, and active pickups. And probably a 5 string, with a 35" scale. I know my amp really sucks. And am i going to have to upgrade that also, if i really want to accomplish this? Also, is there anything im missing? Thanks.
