I recently switched from an ordinary black nylon strap on my Tom Anderson to a really cool, wide brown leather strap with metal studs that I bought at NAMM. I like it, but my tone is now kind of brittle...will it sound better after I get 30-40 playing hours on it? Also I tried out a Bumble strap recently....was not impressed. Probably because it was not custom made for me. I hear Santana and Mayer love their Bumbles.
