Over the last 2 years I've upgraded some of my basses with aftermarket pups/pres, maybe it is of interest for you (I know I was looking all over for these when I was planning my upgrades) 1. Ibanez SR370F with Bartolini MK4CBC pups (wired parallel) and Bartolini 5.2 pre. Elixir Strings(all tone controls at 0) 2. Cravin Icon 6 Fretless (Mahogany body, 5 piece Maple neck with mahogany stripes) with Delano SBC 5 HE/S (wired in series). Elixir Strings (all tone controls at 0) p.s. sorry about somewhat sloppy playing.
