Every now and then a new kind of guitar comes in for me to learn about and experience. Kevin Kopp is a luthier -guitar builder in the Bozeman Montana area. He was at the Gibson custom shop there and now builds under the Kopp name. His website has some of the nicest looking guitars built in the past decade or two that I can think of. This offering is his version of a Gibson AJ model advanced jumbo with Brazilian rosewood back and sides.The headstock also has the vintage look and this guitar was build circa 2011.This guitar is of the highest quality and I would describe the tone as deep and loud.The guitar is used but still in excellent condition free of damage or repairs.
