Kopp RS Roy Smeck. The better 12-fret Slope D. Mahogany back and sides, Adirondack top, Ivoroid binding and bridge pins, Rosewood fingerboard, Mahogany neck, Waverly tuning machines. 1 3/4" nut, 2 1/4" string spacing at bridge. The original Roy Smeck was a square neck. People would send them back to the Gibson factory to have the necks shaved to a round profile. Kevin sent this one out with the neck already rounded, just the way you want it to be. I have been a long time fan of the J body Gibsons from the 40"s. This guitar is not merely a time capsule to those wonderful guitars, it is the next generation and it is where those oldies were trying to get to. The build aesthetic is exactly what it needs to be. The guitars Kevin makes are to be appreciated by the players, as they are imbued with old soul and are destined to become once-in-a-lifetime guitars as they age and season. Mr. Kopp does not have parts machined en-masse. Use of CNC, Fadal, laser, water jet, and robotics can get you lots of guitars. Building them one at a time means the builder uses all his senses and instinct too and the result gets you lots of guitar.
