It's a copy I put together few years ago based on this genuine slab p from '67 with tort guard and lollipop tuners:
slab_pbass67engI used a lightweight 2-piece swamp ash body finished with nitro Olympic White. Fender AV RI '63 pickups, harness, bridge, covers, knobs, pickguard shield. Spitfire pickguard (early one with the thick black ply). Fender Roger Waters neck with gloss urethane stripped, refinished in nitro with repro transition decal. Brass nut replaced with bone. Genuine 60's lollipop tuners and '67 neck plate from my parts drawer.
