I can't possible rake unless it comes back into my thumb. IE, raking from G string to D, I have to rest my thumb on A to catch my finger. Secondly, my fingers have to be slightly angled sidewise, fingers pointing towards the direction of the headstock. And thirdly, when doing long rakes that go across 3 or more strings (IE, Mellowship Slinky in B Major), my thumb starts floating Cliff Burton style instead of just switching to the pickup. Are these problems normal, and if needed how do I fix them?
