So, ok..since I started playing guitar about 2 years ago I've always placed my thumb either over the top of the neck for playing chords where I don't hit the top strings or pretty close to the top for chords where I do. Now I'm curious, will that turn out to be a bad thing in the long run. Will it not develop my hand muscles properly or anything like that? I put my thumb in the middle when I play barre chords and I usually can't get past a single verse.
When the going gets tough, the tough turn pro.
