Fernandes RB-80 it's Japanese early eighties copy of Rickenbacker 4001. Probably this is one of the best 4001 copies on market and has the same with Rick specificacion. Beautiful neck(through body) with triangle inlays, twin truss rods, and same system with two output jacks for stereo sound. I bought black(Jetglo) Fernandes RB-80 in good condition for 500$ and spent extra 80$ for installing of new frets. Guitar was in all original conditions and had some scratches.
