I'm thinking really seriously about three basses, the two mentioned above and the MTD Heir. I've played a Kingston, so I know about all I need to on that one, so I have to ask about the other two. First, what are the necks like on them? I've heard the BB605 described as "chunky," and I know that the BTB is wide, but I'm curious about the thinckness front to back. Is the BB605 full width, or is it just thick? I really want a bass with wide spacing. Also, What is the neck on the BTB made of? Is it Maple and Walnut? Thanks.
