I decided that I wanted to move up a string gauge on my main guitars this week so I put some Gibson Vintage Reissue 11's on this guy. I had them on my Les Paul and then forgot and put 10's on it the week before and discovered how much better that guitar played and felt with the heavier strings. I also play 12's on my archtop but this is a little harder on my hands between the 25.5" scale length, the hard tail and the fact that I play all kinds of things with bends that are either pretty wide or as part of an oblique bend where hand strength is very important.
After last years fiasco of giving myself tennis elbow with the archtop (which I have been fully healed of for some months now) I am going much slower with this transition....less practice time and more breaks between sections of practicing.
This was the video that pushed me over the edge on this.....Josh Smith actually plays 13's in an effortless way and his sound is a lot closer to what I've been trying to achieve regardless of the instrument that he's playing.
