Ok TB I have two Modern Player Jazz Basses. The sunburst is the first production run. The white is the second production run. These bass sound different from each other particularly in the mids and highs. Not dramatically different but enough that I prefer the sunburst tone to the white one. The biggest different that I can think of that would effect the tone would be the difference in pick ups. The pole pieces on the sunburst are basically directly under the strings white the white bass the pole pieces are in between the strings My question is do the location of pole pieces effect the tone of the bass or is it something else?
