The shape is what is important to my hands. Given a choice, logs are the best, but size doesn't matter as much as shape. I'm adjusting to the small size of the Gibson neck, but if it was road kill flat, like a 7ender, it would not be right. The Precision I have is flattened out, but at least the neck has an aircraft carrier deck width, so it's got something going for it. A little Jazz bass noodle isn't my idea of a good thing at all. The small, slightly flattened neck that was on the Rickenbacker is one of the reasons it didn't stick around. If it had been round, like a neck should be, then I might have kept it. Ah, who am I fooling - it would have eventually gotten sold so I could buy a Thunderbird.
