1975-1982 Navigator SA-150
ESP-designed sleek 335
For its antique finish, Navigator wears nitrocellulose lacquer, not the common way for massive production guitars due to much cost and effort. The main benefit of lacquer? the subtle change of natural timber colorization and deeper resonance as the woods are getting dried over the course.
As for this particular model, Navigator SA series 335 types appear in the ESP catalogs only from 1975 to 1984 and the one showcased here is 1975-1982 production. The guitars manufactured around this period are distinguishable by the narrow dots on 12 frets. Navigators from the rest of years have dots distant each other, one on 6th string and one on 1st string.
Trivia for collectors - the model of this guitar is SA-150. ESP advises there is difference of the tuning pegs between SA-120 and SA-150, where SA-120 has brass-made ones while SA-150 tuning pegs were made from bovine bone. Also, pickups must be from Gotoh, judging from S letter imprinted.
