RICKENBACKER made the 4003/S5 bass between 1987 and 2002, it was the 5-string (low-B) version of the 4003 and has a the iconic 4001S body style with flowing body contours. The extra tuner nicely fits into the slightly extended headstock, still maintaining the typical 4000 series headstock shape.The Rickenbacker 4003/S5 has a relatively narrow neck for a 5-string bass (measuring 1.875 inches at the nut), fine for plectrum playing but perhaps a bit tight for comfortable fingerstyle playing if you have big hands or are used to wider string spacing. Pickups are two single coils: a toaster pickup at the neck and a 5 pole piece unit at the bridge. Output is mono. Both neck and body are unbound - the plainer "S" finish (with dot inlays and unbound neck) means that there is more wood left in the fingerboard to help deal with the additional string tension of the extra B string.
