Which neck, and why?

[ELG60]

My tech and I are building a Jazz-style bass. I'm using 1960 stacked and improved controls, a Hipshot Kickass bridge and Klein '62 pups.

Which of these 2 necks do you prefer, and why?

 

[Solarmist]

Maple with dots would look nice.

 

[Reedt2000]

I vote maple. I always loved the binding with blocks look. It just says "this is not an average jazz bass" IMO. If you could laminate the headstock with spalted maple to match the body I'd dig the maple neck even more.

 

[IPA]

Boob', rose, and dots for sure. It carries that sort of 'natural' 'woody' look all the way through. The blocks would look better on a solid color body.

 

[Bassa Nova]

Rosewood. The dark contrast catches the eye.

 

[mbelue]

Bound and black blocked looks best with painted basses IMO.
That beautiful body wood needs beautiful neck wood.

I put blocks on everything, but I don’t dig the maple with this body. Could you find a rosewood neck with blocks? That would get my vote. Otherwise, I’m going with “anything but maple” aka “carrots.”

I take your point. Before the Tru-oil was applied, the contrast wasn't as apparent, BB&B is my favorite ascetic as well but sourcing a rosewood blocked neck at this late stage will be either expensive &/or problematic. It's a bolt-on though so nothing's irreversible.

Thank you to all who have responded so far. Many of your thoughts have mirrored my own.
Here's how it looked prior to application of the finish:

I like the first neck better. The head stock on the second neck doesn’t seem to go really well with the wood the body is made of.

 

[GretschWretch]

If the maple and block is nitro finished and you leave it on there long enough, the neck will turn carrot colored.

 

[ThinCrappyTone]

i like the contrast of the darker neck, but wish the headstock matched the body

 

[FilTurd]

Exactly

[juancaminos]

Maple because...well...that's what should be on a Jazz type bass!

Ha!

 

[BigBear77]

I do love me some Bubinga, but if you are going with a 60’s vibe, I think the Maple neck would look much better.

Yeah, I hear ya. Me too. I doubt it can be bleached.

What's the profile, radius, width, fret wire and finish on them?

Each of those is more important than the visual.

Good point.
They're both standard Jazz width, 1.5" at the nut. As to the rest, I have no idea as to the radii. They both appear to have medium jumbo frets, the blocked is a Warmoth which has a gloss finish, the bubinga is currently unfinished. For me, the neck profile which I like best is that of my 1969, although the slimmer neck on my 64 is not uncomfortable at all. I've really never been conscious of any significant difference in radii on any of my Fender basses, although I do find the slab board on the Peavey T-40 I picked up recently to be a bit off-putting. (besides the damned thing weighing a ton)

Bound Maple and blocks. That looks like a Jazz Bass. IMO, the other one looks like a parts bass. And not a very well chosen bunch of parts, either. Sorry, but you did ask...

 

[DrThumpenstein]

Rosewood brings out deeper, richer colors from that body

Can't go wrong either way, that bass is going to be a beaut. Good luck with the build
