Removing the neck couldn't be easier
For removing the neck, you start with tuning down the strings some turn, so you can remove the bridge. Then, release the strings from the tailpiece (which can stay on the bass). After loosening the neck screw, you slide the neck forward and store it (with the strings) in the neck bag.
The 2-in-1 Gigbag
The softcase for the Christopher RN can be used for both the assembled and disassmbled bass. The removed neck is stored in a seperate pocket, which is slided into the softcase and secured with straps, the empty neck of the softcase is folded. The overall dimension of this package isn't much more than the dimension of the bass body w 70 x l 130 cm: small enough to fit you car's luggage space, train compartment, or even a bike trailer easily.
