I'm thinking about customizing my bass this summer, I can't afford a new one, but I'd like a better sound out of what I have. Also, I just like playing with tools and equipment and stuff. I wasn't sure what forum it went under, so I just put it here. I have a Yamaha RBX260 fretless, and I want to get a new pickup, other than that, I don't know what to do. I've heard that a new bridge could help with sustain, and that some people get new nuts and tuners, could anyone help me out? Right now I play with flatwounds, and I like the smooth sound, but I'd like a little more sustain.
