Jay "Rhyne" Riness (born in 1937) was a luthier who made and restored high-end acoustic guitars (and some electrics) in Decatur, Georgia. Jay also built mandolins, dulcimers, and banjos, but his passion was acoustic guitars. He normally worked alone but during the 1970s lead a team of 8 workers for a while. He stopped making guitars following a stroke in 2000 and he died in 2010.
