Been having trouble with my hand cramping when playing the Sklar. I realized that my strap was just a little longer than the others so body position is slightly different. I was going to move the strap lock up a little, but just grabbed it, put it on the recessed pin and (the key here most likely) without thinking just played. Felt comfortable. I also found that on the Sklar I used to move my hand to the pickups to get a thumb rest. Today I played in my usual position and floated my thumb and generally didn't have to think about it. Did help it was a couple easy songs I was working on, but still.
