Thank you for contacting PRS Guitars. The finish on the necks of the ZM model should be satin. The factory hand sands the neck to create the satin finish, so it would appear that they forgot to sand this particular guitar. If you contact your dealer, they can assist you in getting a repair...
Recently I bought a PRS Zach Myers SE from an official dealer. Nevertheless, rather than having a satin finish neck, it has a glossy finish.
Anyone knows about it? As far as i read through the posts, everyone said the neck is with Satin finish.
