Limitation: Replacement necks may require precise fitting or sanding to achieve a perfect match with the original hardware.

Best for: players needing additional frets on a 4-string bass without changing scale. Caution: May require careful measuring of heel and nut to ensure a snug fit in a specific body pocket.

Buying Guide
- What is your project type? Choose a full kit (like the Fistrock double neck) for a complete dual instrument setup, or select a replacement neck if you are updating an existing guitar or bass.
- Scale length and nut width—match these to your body and hardware. A 34″ scale with 42mm nut is common for 4-string bass necks; shorter scales appear in some 30″ variants and require compatible bodies.
- Fingerboard material—rosewood offers warm, resonant tonal character; maple provides brighter attack and durability. This choice affects tone and maintenance needs.
- Finish and fit—replacement necks often require body pocket fitment, truss rod adjustments, and sometimes sanding to avoid gaps or misalignment. Plan for careful installation.
- Playability and profile—Modern “C” profiles and 9.5″ radii support fast playing and ease of movement. If you prefer a deeper feel, consider other neck shapes carefully.
- DIY readiness—kits are best for builders comfortable with gluing, screwing, and setup; replacement necks are better for those aiming for minimal modification.
