Hey, all. Can we talk fretting-hand fatigue? I'm struggling with fatigue in the thumb flexor of my fretting hand. My hands are pretty small and I play a lot of jazz chords with a lot of barre-ing. I've been trying to address the issue by just practicing more, but I am not seeing a lot of improvement yet. Two thoughts. Option A: I have a technique problem. I'm squeezing the neck too hard, basically, and need to figure out how not to do that. (I should post this on the "hardest thing to learn" thread that's up now....) Option B: perhaps some guitars don't fit my hands as well as others. I have an Epiphone Swingster, and two Gretsches: a 5420 and a 6120. I find that I have less fretting-hand fatigue issues on the Epi than my Gretsches. I think this has to do with two things: neck profile (a little thinner on the Gretsches, and slightly--but not much--chunkier on the Epi), and fret profile (slightly taller frets on the Epi than the Gretsches). But these differences are pretty small, and also it's not that I have zero fatigue problems on the Epi; it's just noticeably not as bad. Seems like it's probably some combination of A and B. Anyone else have this issue? What worked for you? In your experience what's the balance between options A and B--how much difference does "the right guitar for your hands" make and how much is just proper technique and getting your practice hours in?
