My bride recently decided to purchase a guitar for me as a surprise. She contacted Dave regarding an appropriate guitar, and he guided her toward the J28SDL. I could not be more pleased with the beautiful guit or with RGG's excellent service.
The quilted maple back and sides are stunning! The only thing that is more impressive than the way this guitar looks, is the way she sounds. And with the solid spruce top, she'll sound better with each passing year.
Dave, thank you for taking care of my bride, and for a beautiful well made guitar that will some day pass to my grandchildren!
