Worth doing some research on that Washburn as at that date it is likely still a Matsumoku (Japan) built instrument and very decent. That whole hair-metal/poodle-rock/spandex era, which I personally detested, is certainly now very much recognised as its own ‘thing’ and a interesting stage in Japanese guitar evolution. It is certainly becoming collectable. It represents the start of the (still current) phase when they stopped copying/bettering US instruments and went all-out rock that led to enduring classics like Vai’s Ibanez JEM and where things are now. My own favourite point is just before that in the late-70s to early-80s where things like the Ibanez Artist/Musician, Aria YS500, TS, SB1000, Yamaha SG1000, SG2000, SC1200 etc etc arrived, i.e. they’d stopped copying, but hadn’t yet nailed themselves to the hard-rock genre (a lot of these instruments ended up with jazz & soul players). Anyway I bet you have a great playing and sounding instrument there that will only increase in value. I’d not be tempted to modify it at all as good condition totally stock examples of that period are now hard to find as everyone stuck bonkers hot pickups in them etc.
PS Boss Metal Zone and dive-bombing, obvs.
