I am a male just south of 90 years old…have a farm on an Island off the coast of Maine, ( Mount Desert Island) near Bar Harbor, Maine. Love music…play
a mandolin and banjo and have a new Kala concert ukulele. I want to tune the ukulele like my other string
instruments GDAE (so that I can use the same fingering). But am having a very difficult time finding GDAE
strings…got s set from Aquila - but they are bass - thundergut and will not work. I need some help….
