This is a bit of an odd ball. The claim from the previous owner is that it was for an employee of Ibanez and has an Ibanez US Custom shop neck, but I have no way to substantiate that claim. What I DO know is that this is the only ATK fretless I have seen with the gloss finish on the fingerboard, and it did come with a hardshell case that is not included with the low-end ATKs. It's heavy at about 9.6 lbs, but it sounds and plays great. Strung with LaBella gold tapewounds.
