Ive been playing stand up bass for about a year in my jazz ensemble but finally this summer im getting my own, one of the techiqnues i definatily want to learn is thumb position but i dont understand it at all... i try to do what i see other people doing but it just feels painful on my thumb.. is my thumb weak and needs to get stronger or am i doing it wrong? from what i see you just use your thumb sorta like a capo and push the strings down with the side of your thumb
