Crews Key To The Rock models are exclusive to the Musicland Key store in Japan.
The KTR Next 5D is a Limited Edition 50th Anniversary model. 20 were made in total. It is nicely spec'd true to a '58 style Les Paul. The neck is fat and the frets are tall and thin.
The body is one piece mahogany and the mahogany used for the neck has been air dried for over 30 years. The maple top has a nice subtle flame to it and finished with a lovely vintage burst.
Beyond the fact that the guitar is easy to play, it is equipped with a set of my favorite pickups, K&T NFS Weeps (ZB/WW). They have all of the spank and clarity that define a great set of low output PAF style humbuckers.
Weight is 9.4 pounds.
Neck measurements are:
Width - 1.70" at the nut, 2.07" at the 12th fret
Depth - 0.89" at the nut, 0.98" at the 12th fret
