First up, I have a musical background, I can read music, I know about scales and chords and whatnot cause i've been around guitarists for years. But i'm just starting bass, and I have some questions: 1. Where should callouses be forming, specifically? Cause I have one forming on the side of my thumb on my picking hand, and on the tops of my fingers (naturally) on my other. Should I have any on the fingertips of my picking hand? 2. Well.. just any general tips? For starting out? I sort of lost my train of thought. Thats what drummers do.
