4 Strings Jazz Bass Compatible Guitar Neck Roasted Maple Neck 12" Radius 18 mm Holes 20 Frets Satin Finish

Product Overview

Built for four-string Jazz Bass-style basses, this replacement neck pairs a Canadian roasted maple neck with a matching roasted maple fretboard, a rosewood skunk stripe and a smooth satin finish. The scale, fret count and radius follow the familiar Jazz Bass pattern, so the neck feels at home on a repair bench, a parts build or a personal upgrade where the original is worn, damaged or simply due for a change. Because the neck and fretboard are both roasted maple, the response is clear and articulate, with the natural look of heat-treated wood rather than a dark fretboard. It is a replacement part, not a complete instrument; it is built for Jazz Bass-style bodies with the dimensions listed in the specification table. Every electric guitar neck we make starts from hand-selected A-grade Canadian maple and is finished in our own workshop.

Roasted Maple Construction

Why roasted maple Roasting drives moisture out of the wood and leaves a more stable blank, which is why roasted maple necks hold their shape through seasonal humidity changes and long travel days. On this maple guitar neck the neck and fretboard are both Canadian roasted maple, so the feel is consistent from the back of the neck to the playing surface. The grain is tighter and darker than raw maple, giving the instrument a warm natural look without a tinted lacquer. We hand-select A-grade Canadian maple for these necks and keep the finish thin, so the wood still feels like wood rather than plastic. Rosewood where it belongs The dark strip on the back is a rosewood skunk stripe, not a rosewood fretboard. Rosewood is usually chosen for a warm, smooth feel and a slightly softer top end; here it is the insert that covers the truss rod channel and adds a traditional dark line against the maple. The playing surface stays roasted maple, which keeps the response quick and the look bright and natural. The board carries simple dot position markers, so the look stays clean and easy to read on a dark stage. Width and profile The guitar neck width at the nut is listed in the specification table, and the modern C profile sits comfortably in the hand for both thumb-behind and thumb-over players. From there the neck carries a middle-ground radius that supports chord work and still allows string bending without choking; the thickness grows gently from the first fret to the twelfth rather than jumping at the shoulder. Profile in hand Among common guitar neck shapes, this is the one to choose if you want a familiar bass feel rather than a deep, clubby profile. The shoulders are rounded rather than square, so the thumb can sit behind the neck without a hard edge, and the board stays comfortable when you move up the register. Finish and feel The satin finish is the part your hand notices first: it glides without the stickiness of a high-gloss coat and keeps the neck looking understated. It is thin enough to show the roasted maple grain, and it does not need to be polished to stay smooth. If you prefer a gloss neck, this is not that feel; if you want a fast, dry surface for long sessions, it is the right choice.

Fretwork & Playability

• Frets are pressed at the scale length so every fret sits level with its neighbours before the tops are shaped.
• Fret ends are rounded and beveled so they sit flush with the fretboard edge and do not catch your hand during fast passages.
• The tops are hand-polished and crowned into their final form, which gives clean note release and avoids the scratchy feel some replacement necks have.
• Fretboard edges are smoothed and rolled enough to feel broken-in, with no sharp corners where your thumb travels.
• The truss rod runs under the skunk stripe and adjusts in both directions, so you can correct a concave or convex bow as humidity changes.
• The electric guitar neck length is set by the scale, so the frets land in the familiar Jazz Bass positions rather than a shortened or converted layout.
• Small guitar neck parts — nut, frets, truss rod and skunk stripe — are checked together before the neck leaves the bench, because a single high fret or loose nut ruins the first setup.

Jazz Bass Fit & Compatibility

What it fits This is a four-string Jazz Bass-style replacement neck, built around the scale length, heel size and peg hole spacing shown in the specification table. It is not a conversion neck, so the body's neck pocket and bridge position need to match those figures. Measure the pocket width at the heel, the pocket depth and the distance from the pocket to the bridge saddles before you order. If your body is drilled for a different heel or tuner spacing, this is not a drop-in fit. Dimensions to check The electric guitar neck dimensions that decide fit are the nut width, heel width, heel depth and peg hole diameter; compare each one with your body and tuners, not just with the model name. A dry fit before tightening screws will show any gap or tight spot while it is still easy to fix. Width at the nut The guitar neck width at the nut affects string spacing at the first fret, so check it against the sound you want and the strings you use. A nut that is too wide or too narrow changes how the bass feels under your fingers, even when the heel fits the pocket. What it is not It is not a universal neck and it is not an official Fender or licensed replacement. "Compatible" means the dimensions line up with a Jazz Bass-style build, not that every bass will accept it without checking. For a repair, confirm the original neck's scale and pocket with a ruler rather than relying on the model name. For a new build, match the body to the scale length and bridge location before you choose pickups or strings.

Installation & Setup

1. Check the pocket before you fit anything. Remove the old neck, clean the pocket, and compare the new heel to the pocket with the neck unstrung; the guitar neck shapes should sit flush without forcing.
2. Test the tuner holes. Offer up the tuners you plan to use and confirm the bushings seat without wobble; if they are loose or tight, stop before pressing anything in.
3. Mount the neck. Fit the screws finger-tight first, check that the neck sits straight in the pocket, then tighten in a cross pattern so the heel does not lift at one corner.
4. String up and check relief. Tune to pitch, then use the truss rod to set a small amount of relief; turn in small steps and let the neck settle before measuring again.
5. Set action and intonation. Adjust bridge height and saddle position after the relief is right, then check the first few frets for buzz and the octave at the 12th fret.
6. Check the small guitar neck parts before the first session: the pre-slotted nut, fret ends and truss rod should all feel right, and any high fret will show up as a buzz on one string rather than all of them.
7. Deal with minor fret movement. The neck may need a light fret dressing or leveling after shipping or to meet a very low action; this is normal for a wooden neck that has travelled, and it is a small bench job rather than a rebuild.
8. Play it in. The electric guitar neck should feel comfortable after a day or two of settling; if a fret starts to buzz or the relief moves, recheck the truss rod before changing anything else.

Tone & Playing Feel

In the mix A Jazz Bass often has to sit between a kick drum and a guitar, and this maple guitar neck feeds that role with a clear, articulate top end and a controlled low mid. Notes have a quick attack, so fingerstyle lines and slap passages speak without a mush of overtones. It is not a dark, woolly neck; if you want a softer top end, a darker-board version will feel closer to that. Fingerstyle and pick The flatter board gives you room to dig in without the strings choking, and the fretwork keeps the upper register comfortable. With a pick, the finish and profile let your hand move without drag; with fingers, the smoothed edges make long sessions easier. The neck responds well to changes in right-hand attack, which is useful on stage when you need to go from supportive to aggressive without touching the amp. Studio and stage In a studio, the clear fundamental makes it easy to place in a mix without heavy EQ. On stage, the stable roasted maple helps the neck stay put through warm lights and cold load-ins, so the setup you leave the house with is closer to the one you play. This guitar neck is not voiced like a vintage-style bass with a soft, dark blanket over the top; it is more open and immediate. String and setup choices Flatwounds will mellow the top end and emphasize the low mid; rounds will bring out the articulation. A slightly higher action suits heavy fingerstyle, while a lower action rewards a light touch, but the neck may need a fret dressing if you want the strings very close. Let the bass tell you what it wants after the first setup rather than forcing a number from another instrument.
