i am looking for a growly bass. what exactly makes a bass growly? is it the pickups? wood? electrionics? i have a flea bass and a stingray but im wanting something different. i really like that growly sound of flea's wal bass on bssm, but wal's are too expensive, i also like dirk lance's tone on the science album. can anyone reccomend something (besides fender) that costs around $1000 new or used that fits the bill? sorry if im being too general. just anything growly and thick sounding.
