I've preferred Jazz necks from the get-go. For me, the main reason is the slightly tighter string-spacing. It allows me to switch/reach from string to string with a little bit more efficiency and physical economy.
However, I found out the hard way that not all Jazz necks are equal.
When I put together my first parts-bass project, I used the neck from a Squier Deluxe Jazz. I loved the look of the smooth, all-black, ebonol fretboard. Plus, it had a black painted headstock…a big
"Hell Yeah!" for me. I was also intrigued by the purported toughness and "resistance to humidity" of the ebonol. Unfortunately, I could seem to fully bond with it. There was
"something" not quite right with it that I couldn't peg down.
Later that year, I decided to dig my Aerodyne out of it's dormancy and take it with me on a short trip. Once I started noodling around with my 'Dyne, something I hadn't done in many months, I had an epiphany!
(as opposed to an Epiphone
) That
"something" I was missing with my parts-bass was in the neck. So, I called up the specs of both basses for comparison. As it turns out, it was the
fretboard radius that was radically different.
The 'Dyne has a curvier, vintage-style, 7.25" radius, while the Squier Deluxe has a much-flatter, modern-style 12" radius. All the other basses I'd owned up to that point had a 9.5" radius common amongst most Fenders. To my hands, going between 7.25" and 9.5" is an easy transition, but the curvier ones are more comfortable.
On the upside, I stumbled upon a crucial criterium when shopping for instruments and necks. Now I know for certain what my fretting hand likes. Sure, it eliminates a number of possible "exploratory purchases", but if nothing else, it's a great tonic for GAS!
P.S.: If anyone is thinking
"just keep practicing on other necks…you'll adapt", there are circumstances in my life that say otherwise. Specifically, I'm a professional massage and neuromuscular therapist. I can ill-afford to inflict any unnecessary cramping on my hands that would come with forcing such a transition. So, I'll stick with what I know my hands prefer.
