Mahogany neck, all metal parts, 500k pots, coil tap pickups, wicked raw aluminum finish. For the price, the materials are worth it. Needs a wiring diagram. But overall I loved what I got. Used 400 grit sandpaper lightly on the fret edges to polish the jags off. Polished the entire neck with fine grade steel wool. I can't wait to get it assembled!Update: Ass with any DIY there is some work involved. I had to do some fret filing from the 12th-24th frets. I found the wiring diagram too, attaching it to this. I love the rough finish I may do some smoothing and rounding modifications and buff it out. The stock pickups are actually quite nice. I just might have to get another one! Just another FYI: this guitar finished and assembled is around $800 delivered from Koloss. There is much unfinished with it, but what fantastic bones! I love the crazy long sustain and resonance of this body!No instructions in box and none on company website. Videos and pdfs for all the wood guitars but not the aluminum ones. Two and a half hours trying to put the pickups in which is the first thing I’ve tried. Bridge pickup doesn’t even fit in hole no matter what angle or front or back of body. No room to hold spring or pickup while trying to put screw in neck pickup. Now I know why there’s no instructions. Beyond frustrated at this point. Was so excited about getting this guitar and now I’m so disappointed….
