5-string neck profile and radius availability

Postby Ezn73 » Wed May 29, 2019 3:05 pm

I'm considering an option order M-2500 fretless with an unlined ebony fingerboard.

Does anyone know which neck profiles and radii (radiuses?) are available for such a build? Or, are there only certain possible combinations for 5ers?

I apologize if this has been asked/answered in the past. I did try searching, but what I found was several years old, and specs are always subject to change.

Here they are listed for convenience:

NECK PROFILES
1 5/8” Medium C
1 5/8” nut width sits right between the traditional P and J bass widths, and Leo offered this nut width in the ‘80s. Generous edge roll with a medium depth and taper from 0.820” at 1st fret to 0.940” at 12th fret. These specs were part of the #11 and #12 necks.
ORDER CODE: 12NK

1 1/2″ Medium C
1 ½” nut width traditional to a J bass, Leo brought it with him to Fender Avenue for the ASAT Bass and SB-2. 1 1/2” nut width, generous edge roll, and medium taper from 0.820” at 1st fret to 0.920” at 12th fret. These specs were part of the #6 and #8 necks.
ORDER CODE: 8NK

1 ¾” Medium C
1 ¾” nut width traditional to a P bass, Leo brought it with him to Fender Avenue for the L-2000 and other models. 1 3/4” nut width, generous edge roll, medium taper from 0.820” at 1st fret to 0.940” at 12th fret. These specs were part of the #5 and #7 necks.
ORDER CODE: 7NK

1 ¾” Medium C 5
1 ¾” nut width, generous edge roll, medium taper from 0.820” at 1st fret to 0.940” at 12th fret. Starts out just like the 4-string 1 ¾” medium C and fans out to a wider heel. These specs were part of the #10 neck. For 5-string basses only.
ORDER CODE: 10NK

Modern C 5 omitted because it's "Exclusive to the JB-5"

NECK RADIUS
7 1/2″ ORDER CODE: R75
9 1/2″ ORDER CODE: R95
12″ ORDER CODE: R12

Right there are your neck dimension options for a 5 string. It's the same as the old-spec #10 neck; 1 ¾” nut with a 12" radius.

Darn, was hoping for something thinner with maybe a 9.5" radius. Fretless-wise I'm used to my super-thin MIJ Fender Jazz.

As usual, thanks for the info, Ken.

Here's an option for you to consider:

Scrape around for an old, and somewhat rare, L5000. One of the reasons it wasn't particularly successful was because they crammed 5 saddles into a 4 string bridge along with a narrow nut.

As much as I hate to say this about a true rarebird, you could carefully de-fang the neck and have yourself a fretless 5-er. All you'd have to do from there is get used to the narrow string spacing.

The other option, if you're feeling adventurous, is to get a sanding block in the radius of your choice and have a go at reshaping the fretboard.

(Or have a professional do it.)
