12 String Guitar Neck Maple — 25.5″ Scale
Best for: DIY builders who want a maple neck with a rosewood fretboard. This neck is unfinished, allowing full customization of finish and nut slots. The 25.5″ scale length is standard for many 12-string configurations, and 22 frets provide access across the fretboard. Note that it is a straight neck option without inlays, so a builder may want to add position markers during setup.
BexGears 12 String Kit — Mahogany Body
Best for: Builders who want a complete 12-string package with a mahogany body and maple neck. This kit provides pre-drilled holes and all parts needed to assemble a playable guitar, making it suitable for beginners and intermediate builders alike. Limitation: right-handed versions only, which may not suit left-handed players unless modified.
Wide 12 String Neck — 24.75″
Best for: Players seeking a wider neck profile with a rosewood fretboard and a beveled edge for smoother playability. The 24.75″ length sits in between standard long-scale designs and shorter options, offering brighter tone and sustain. Limitation: neck is unfinished and may require setup and finishing by the builder.
Fistrock Double Neck Kit — 6 & 12 String
Best for: Enthusiasts planning a dual-neck build, combining a 12-string neck with a 6-string neck in one instrument. The kit includes mahogany body, rosewood fingerboard, humbucker pickups, and hardware, making it a comprehensive project. Limitation: requires substantial building, finishing, and wiring work; not ideal for first-timers.
12 String Paddle Head Neck — 24.75″
Best for: DIY builders who want a paddle-style headstock and full control over headstock design. The neck features a maple shaft with a rosewood fingerboard, 24 frets, and a 24.75″ scale. Limitation: requires a custom headstock routing and drilling for tuning pegs, which adds to the build complexity.
Leo Jaymz Neck — 12″ to 16″ Radius
Note: This item is included for reference as a comparator to a 12-string neck choice, featuring a compound radius and Canadian hard maple neck. Consider this when evaluating options for comfort in open chords versus fast leads. Best for: players seeking a versatile radius option on a maple neck; avoid if you only need a pure 12-string neck with a fixed radius.
Buying Guide
What to prioritize when buying a 12-string neck
- Scale length: Commonly 24.75″ or 25.5″. Longer scales deliver brighter tone and more tension; shorter scales ease string tension.
- Wood type: Maple necks are stable and bright; rosewood fingerboards add smooth feel and warmth. Unfinished necks require finish and setup.
- Fret count and finish: 22 frets are typical for 12-string necks; beveled edges and rolled fret ends improve playability.
- Headstock design: Paddle-head designs offer customization but demand extra routing and peg placement work.
- Kit versus bare neck: Kits simplify assembly and wiring but may limit customization. Bare necks maximize customization but require more skills.
For DIY builders: Which choice fits your project?
- Full-kit options (like BexGears) suit beginners seeking a complete build with minimal sourcing work.
- Bare necks (maple with rosewood fretboard) are best for builders who want a custom finish and precise setup.
- Double-neck kits are for advanced builders aiming for unique instruments with multiple tunings.
Considerations for compatibility and setup
- Bolt-on versus set neck: Most replacement necks are bolt-on; confirm compatibility with your body and bridge.
- Nut width and heel size: Ensure nut slot width and neck heel fit your guitar body to avoid misalignment.
- Finish and maintenance: Unfinished necks require appropriate sealing and protection to prevent warping.
Maintenance tips
- Seasonal humidity can affect neck stability; store guitars in stable climate.
- Regular truss-rod adjustments help maintain optimal relief and intonation on longer 12-string necks.
- Cleaning fretboard and applying conditioner on rosewood surfaces helps preserve playability.
FAQ
- What is the typical scale length for a 12-string neck?
Most are 24.75″ to 25.5″; choose based on tension and tone preference. - Are unfinished necks ready to play after finishing?
Unfinished necks require sealing, fretwork, nut installation, and setup before playability. - Is a double-neck kit appropriate for beginners?
No. Double-neck builds require more advanced skills in routing, wiring, and setup. - Do these necks fit all 12-string body shapes?
Compatibility depends on heel size, bridge mounting, and screw hole pattern; verify with your body. - Should I choose a paddle head or standard headstock?
Paddle heads offer customization potential but require extra routing; choose based on desired look and build plan. - Can I install these necks on existing bodies?
Yes, if the body accepts bolt-on necks and the neck heel and mounting pattern align with the body.
