Prototype US5 RADIUS Bass Guitar P-6


5 String. 100% Performance

This NS US5 Prototype RADIUS Bass P6 is the first RADIUS bass guitar made with a thick fiberboard stripe, a fully compensated bridge saddle and 18mm spacing at the bridge. Designed by NS Founder Ned Steinberger and built in close collaboration with Jon Kelsey of JK Custom Woodworking in Maine. This prototype bass, along with seven others, were the original set of prototype instruments built purposefully for the research and development of Steinberger’s award winning NS RADIUS Bass manufactured and sold today.

While the NS RADIUS Bass Guitar carries forward the heritage of the headless design which was pioneered by Ned Steinberger, it also takes the electric bass to an entirely new level of performance, playability and aesthetic appeal.

The instrument purchase includes a deluxe gig bag, owner’s manual and tool kit.
