For Sale: 2022 Rickenbacker 4003AC Al Cisneros Signature Walnut Bass – Limited Edition (1 of 420)

Up for sale is a 2022 Rickenbacker Limited Edition 4003AC Al Cisneros Signature Walnut Bass, complete with the original hard-shell case. This instrument is in mint condition, exceptionally clean, and operates flawlessly.

The 4003AC was crafted in collaboration with Al Cisneros of Sleep/OM, and only 420 were ever produced. It features a walnut body, a through-body maple neck, and a maple fingerboard with custom green “Sleep” triangle inlays. The 33.25" scale length makes it uniquely comfortable, while a pair of hot-wound treble pickups deliver massive low end and shimmering clarity. The bass also sports a custom Al Cisneros pickguard, a removable thumb rest, and Rickenbacker’s re-engineered bridge and tailpiece for improved stability.

Other key specs include a nut width of 1.71", a slim neck profile measuring .86" at the 1st fret and .89" at the 12th, Schaller Deluxe tuners, a two-way adjustable truss rod, and the signature oil-finished walnut body. Electronics follow the classic 4003 layout: two volumes, two tones, and a 3-way toggle with mono output.

This example remains 100% factory original with no cracks, repairs, or modifications. The neck is straight, the frets show no wear, and it has just been professionally set up here at Guitar Chimp for ideal action and intonation. The bass weighs in at 8lbs 14oz.

The original hard-shell case is included and functions perfectly.
