I took my Gibson J-15 down to get set up with a Bone Saddle and Nut with a K & K Western Pure Mini and Jumbo Fret wire 118x058 Jescar Gold
I learned about the Jumbo Fret Wire enhancing the sound of guitars "Mostly Old Martins"
from Dan Lashbrook
So I found a Guitar Tech in Van Nuys Ca "Eric's Guitar Shop" http://www.ericsguitarshop.com/ Eric did a excellent job on all the work
I picked it up today and I'm very happy with the sound, my J-15 was very good sounding before but had some odd sounding mid frequencies that I hear on a lot of newer J-45s with Tusq Saddles after the setup I'm thrilled with how it plays and sounds "arguably" more 1930 Gibson sounding
