Neck through, maple and mahogany, ebony fretboard, probably from the late 70s. Currently trying to get more info from Yamaha. A little scratched, but nothing too horrible. Most of the worst is on the sides and back.
It arrived in tune, the tuner buttons are a bit loose but the tuners themselves are rock solid.
The guy I bought it from had it set up in C, which was fun for doomy goodness but I went back up my usual D and started fucking around with the height of the pickups. The neck is gorgeously creamy, but the bridge was a little thin, someone had lowered the screws below the top and bottom strings to tame them a little, seems the pickup's have a litle scoop to them. After mucking around for a few hours I think i got it to a place where I could get some metal muscle out of them in addition to the impossibly pretty clean sounds, the pups seemed positively restrained after being used to the chaos of the dirty fingers in my sonex, aha. Also adjusting to the painted neck might take a while, this is about as "show-y" a guitar as I can deal with.
It needs new pots for sure, the tone knobs do pretty much nothing and the volume rolls off nearly completely below 7, I think all the travel in the pots has moved to the end of their sweep... but i'm super stoked. This thing sounds amazing and can only get better.
