Thread: First Build - Mossy custom 27' neck

    First Build - Mossy custom 27' neck

    Hi,

    I am unsure regarding the neck scale check. I am measuring as per the manual instructions (nut to 12th x 2) but do not seem to get the same scale length as noted with the kit.

    Any help appreciated?

    I think I got it. The neck has a zero fret so measured from center of zero fret to 12th and got the scale to match - 685mm

    If the bridge is slanted - where do I take the measurement to from the crown of the 12th fret?

    You measure from the zero fret by the 'high E' (thin) nut slot (or what would be the E string on a standard guitar but is variable on a baritone) to the 'high E' bridge saddle. The intonated length for that string will normally be around 1.5mm longer than the nominal scale length. The 'high E' saddle will always be the furthest saddle forwards, so always use that.

    Hi, thanks Simon.

    The bridge poles are pre drilled...I was looking to confirm that..

    I move the neck in the pocket forward or back, in this case back, fill the gap with a shim to achieve the correct scale length?

    Looks like I have to move bridge back to get the scale correct. Otherwise the gap is too big and the pickguard will not cover it.. having trouble uploading pictures

    Pics need to be no bigger than 1500 pixels on any side and just under 1Mb in size for the forum to host. Otherwise host remotely (e.g. using Imgur) and link to the picture (not the web page its on) using [img] tags.

    Difficult to understand exactly what's going on without pictures.

    Below, first image, shows where the bridge must move to, to achieve correct scale - 685mm

    approx. 15mm gap at neck pocket as shown below if moving neck back to get correct scale length from 12th crown to center high string side of bridge

    Pick guard will not cover without cutting away end of neck pocket, its less than the 15mm, so not a option i think

    Can you show a photo of the whole neck?

    Also, is this a baritone kit, or a standard kit with an add-on baritone neck?

    There are two types of baritone neck, 'standard', made to fit a specific baritone kit (which is what I suspect yours is) and 'conversion' baritone necks to fit on a standard body (standard and conversion are my terms).

    A 'standard' baritone neck has the same number of frets as the body, but the body is made with the bridge and bridge pickup a bit further away from the neck to compensate.

    A 'conversion' neck is longer and has extra frets to compensate for the extra length required when fitted to a standard body.

    A 27" scale means that the scale length is 2.25" longer than the standard 24.75", or 9% longer. So its a bit like just making the guitar 9% longer overall. So if you keep the same 22 frets as the standard neck has (ignoring the zero fret), then the distance from the end of the 22 fret to the bridge also has to increase by 9%. Fine if it's fitted to a body designed for that neck where than distance is longer. But if you fit that neck to a standard body, then you haven't got that extra length built in, and you get to the situation you are in, with the bridge being too far forwards for the scale length.

    A 'conversion' neck adds that extra 9% of required bridge distance from the neck, to the length of the neck instead, so that the overall scale length is correct when the neck is fitted to a standard body to make it a baritone. For a 27" neck, the extra length isn't huge, and rather than have a large expanse of blank fretboard at the end of the neck, an extra fret is normally added to make it appear as normal.

    With that neck, you really have no option but to drill new post holes and fill in the originals. You may find that the stop tailpiece is a bit closer to the bridge than is ideal, so you could move that back as well, or else keep that where it is and string the strings backwards and run them over the top, to save having to have the tailpiece set really high in order for the strings not to foul the rear of the bridge.

    See picture of neck below and some others for context. It has 22 frets.

    I ordered the standard Mossy kit with 27' scale neck, I would think then the bridge needs to be moved so..
