I recently picked up a new cheap bass (of a brand very popular here) and I'm trying to get it set up nicely. At present, with the strings at reasonable playing height, the bridge is at the upper end of its adjustment range---it's a traditional Fender-style bridge, and the allen screws that set the saddle height are all screwed into the saddles to the point where they are below the tops of the saddles, although they're not all the way through by any means. Is that having a negative effect on tone? And if so, would I be better off putting a shim in the neck pocket to bring the bridge back down to the middle of its adjustment range, or would that have a greater negative effect on tone? I hope that made sense. Opinions and advice appreciated.
