I forgot the best reason for the JB in the neck. Phil Keaggy has a Zion Radicaster that has 2 JB's that can be series, parallel, or split. It is an extremely versatile guitar, and I think he uses it to this day.
I think I might try a JB in the neck now you mention that jeremy. I like thick soloing tones, just not too thick. I like the soloing tone to be 'sharp' enough to cut through the rhythm tone.
