The Navigator is in overall good condition, shows play wear and is used. Some small dings on it as well. Plays well.

I believe it may be the LPS-150

The neck looks to be one piece. There are a couple of pieces laminated to the head stock on the outer edges of the center to give it it's shape. The instrument plays very well and it is a set neck, so it does have a classic Les Paul type of sound.

Pick-up stamp on the back 16813 (neck) and S 16813 (bridge) no other defining markings. Maxxon pickups likely.

Two piece body.
Rosewood fingerboard
24 3/4" scale
1 5/8" nut width

Tenon does have a tang below the neck pick-up that runs through the neck pick-up cavity.

Navigator circa 1980 - 1983 by ESP
