So I bought a bass off a guy, all fine and dandy, nothing shady. Some minor dinks which he was honest about. Honestly I cant remember if he told me, but, he filed the nut down on the bottom 2 strings. The main issue being the bottom string, he filed it down to fit a .170 and I use a .135. The gap I have is literally enormous, and my open note sounds like a tinny metallic fart. Not really what I want and I would really like to take this bass out on shows! Ive been looking for a replacement nut, Ive gone to the Ibanez parts store and found the part I need but its labelled discontinued which baffles me. I really need help either locating the original stock replacement nut, or someone point me in the direction of resolution. UK based if that makes a little difference. Note: I have already been told to contact Headstock Distribution to see what they can do.
