I took advantage of the Euro being low at the moment and ordered this Passive 30" Elwood C. Always wanted a sparkle finish Bass. I ended up choosing the Marusczcyk Jazz pickups after watching a few Public Peace videos of them on some builds. I think they will be fine for passive pickups.
Alder body (silver sparkle), Maple neck/fretboard, 1.5" nut, 9.5" radius with Black sparkle inlays and Hipshot hardware.
