Two years ago, I brought my Martin D-18 retro to luthier, Claude St. Denis at St. Denis guitars and he set it up, beautifully.  Since then Claude has become my guitar Tech. And has completely rebuilt my 1972 Harmony.  Claude did such an incredible job on my harmony and has unparallel attention to detail in both guitar repair and guitar building.   Since I have met Mr. St. Denis, I have had the pleasure of playing a dozen St. Denis guitars and every single one is a masterpiece.  If you are ever in central Ontario please take the time to stop by his shop for a tour.
