I have a stingray 5 and my b string always sounds tinny so at the bridge i took the things that hold the strings with the springs on them (i have no idea what they are called) and i lengthened the b string one. And next to that thbing thers a little thing that is a cylinder with a hole in it for anallen wrench. I put the string holder on top of that thing and it stays there but i don't know if this is bad for the bass. Sorry if you don't uinderstand i tried my best to explain. It helps if you have a stingray.
