So I just got an Ibanez ATK300 recently and the tone off of it is just flat out perfect for me and it plays like a dream except for 1 thing... there is no good place to anchor my thumb! Sure, I have practiced with a floating thumb, but it makes me feel... nervous? I feel like I need to anchor, at least for now. So, the question that I would like to pose is this: Should I get a thumb rest and add it on, or should I just deal with it?! Normally I anchor on the pickup, but this pickup is convex and there is no where good to anchor... it is the weirdest thing. I was doing fine until we ran "One way out" at speed and my thumb just kept sliding up under the E string... ugh! Ox.
