I have an opportunity to purchase a 1985 710 (Lemon Grove built) in very very good original condition...including nut /saddle/tuners etc. I notice this has a 3-piece back and a Martin type ebony bridge unlike the newer smiley bridge. Did these early ones have Tusq saddle and nuts? How do these sound compared to say a 90's 710 in terms of volume & tone /bass/fullness/clarity/resonance. Does anyone have one of these or has anyone played/compared them?
