Here’s an excerpt:
I’m using .13 to .70. We’re in baritone tuning…so it takes a tighter string, a heavier gauge to get up to pitch….I went to the wonderful people at the Jim Dunlop [and] went through every string individually to find the correct gauge for bending and wound up with a custom set that goes from .13 up to .70. It’s quite heavy, its almost like a bass string.
