I'm struggling to understand the rationale behind that one. I'd have expected a gross difference between the two necks like 4/5 string or fretted/fretless.
Is it the fingerboard/neck woods that make such a difference between necks, or the brand of strings ?

Can't speak for the owner....but recall he was seeking a dark tone and a bright one. I'd go for a bit more difference. Not sure you would hear much difference except in a solo environment.
