Hi all.
New to this forum and been reading up on the Steinberg Spirit strap mod thingy, having bought an XT25 this week. In agony after using it for a 4-hour rehearsal, I just moved the strap button from the end of the guitar to about 4 inches from the end, and about an inch down from the top (fitted it on back of body) - magic! At least now I can see the lower frets with my failing eyesight, and I'm not playing 2 frets higher than I think I am. Time will tell if it's a comfortable fix, but I'm hoping so!
