Difference in 32" neck dimensions

    For my next build I'm planning to go with a 32 inch scale 4 string.
    What I'd like to understand is how the rest of the neck dimensions are affected by making the neck shorter.

    If the nut is the same width, is the neck taper different?

    Does this change the width of the neck at the pocket?

    Any information that you can offer would be greatly appreciated.

    Oh, I'm assuming that pickup placement needs to be adjusted to accommodate the shorter scale as well, right?

    Everything will be 0.94117647 (32/34) of what it usually is. But you can still decide what you want your nut width, bridge spacing, and neck profile to be.
     
  3. I've built a few 32's. I use all the same dimensions as a 34" jazz bass- nut width, heel width, string spacing at nut and bridge... just make the scale length shorter. I use a constant thickness from nut to heel, but that's just how I like them. You can change all of it, or none of it. Those numbers are all just preference.

    On the 32" I've built I decided to scale down everything, including nut width and spacing at the bridge (used Schaller 3D, it allows for 18 mm spacing)

    The dimensions change only a slight amount from a 34 as Barnaclebeau stated. I am doing a 32" 5 string Single Cut, with a 17mm ABM piezo bridge, and the dimensions of 1.75" @ the nut and 2.75" @ 24 are still the same, basically gaining about 1/64" on each side of the fb, so it's very similar.

    I have completed about twenty 32's and I always just use the same Fender Jazz specs but with the shorter scale. I also like to use 26 frets on my 32's just so the neck feels a bit more like my 24 fret 33's and 22 fret 34's. 1.5 inches at the nut and around 2.5 at the highest fret depending on the number of frets. With these specs I get a little space on the outside of the strings so that I can do a nice rolled edge without getting too close to the string path. Just the right amount of space without looking or feeling goofy

    I have a question about neck width starting from the nut to the 22nd fret. Im building my first bass using a 35" scale. Currently my neck is all squared up and the width is 2 3/8. I know I've got plenty of room at the nut position, but am I under where I need to be at the body? This is a neck thru design. Im learning as I go relying on my last 18 years as a custom cabinet and furniture maker, but this is apples and furniture is oranges! Thanks John

    Decide on your desired string spacing at the nut, and mark it. Decide on your desired string spacing at the bridge, and mark it 35" from the nut. Connect them with lines. Leave 2 or 3 mm on each side outside those lines; this is where your neck is.

    I've never done a neck through, but I'm assuming that the neck taper stops at the point at which the body wings connect, and from there through the rest of the body the "neck" sides are parallel. But there's no hard and fast rule here - if you build it differently and it works, then you win!
