Hi all. I have made many instruments over the years and always shaped necks with a symmetrical profile. A while back I worked for a luthier who shapes his necks asymmetrically. If memory serves, the DG side was thinner than the BE. Does that sound right? 1: When I play, my thumb doesn't really go near the lower side of the neck. In fact it lives mostly on halfway or just above. (I'm a pro player with decent technique.) 2: I have set up many 10+ year-old basses in my time, and most have developed a slight twist towards the treble side. IOW, more relief on the G than on the low B. So why remove material from the treble side? Wouldn't it make more sense to have a thinner EB side? Cheers.
