I got to wondering about comparative neck sizes. A little while ago I succeeded in tracking down a Hagstrom BJ12E. The well known 12-string line on Space Odyssey was played by Bowie on a BJ12.

Everyone says how huge the neck is. And it certainly feels it, compared to more modern 12-strings.   That's string spacing of 45 mm, neck width 51 mm, and neck depth to top of string at nut of 26mm. Compare the J-45 (6 string, Hagstrom not Gibson) which has 35, 43, and 22.

How does one usually measure neck depth? The BJ12 feels very deep as well as wide (like the River Jordan in spiritual!) but the depth doesn't measure as huge as it feels.

THe BJ12 seems to have very stable tuning compared to other 12s - ie it tunes and stays in tune (very odd!). Do we think this is likely to be due to the neck size?

How big is yours?
