Buying Guide — Key Purchase Considerations
What material should I choose?
Acrylic templates offer visibility and rigidity, helping precise alignment. MDF options can be cheaper and adequate for simple projects, but acrylic reduces the risk of mis-cuts due to line-of-sight during routing.
Which template size fits my guitar?
Check outer dimensions and thickness. Most templates in this list are either 150mm x 100mm or similar Jazz/P-Bass sizes. Ensure your body cavity plan matches the template’s measurements and your router’s capability.
Best use case—pickup cavities or neck pockets?
Use dedicated templates for neck pockets (Jazz/P-Bass) and pickup cavities (P-style, Jazz, or Humbucker). Mixing templates can lead to misalignment. When in doubt, choose a template set that covers necks and pickups for the same instrument family.
What are common limitations to expect?
Some templates are designed for open-style Humbuckers and may not accommodate sealed or closed models. Check the template’s notes for compatibility with your pickup type and pickguard design before routing.
How does visibility affect accuracy?
Templates with clear acrylic let you see the body beneath, aiding precise placement and avoiding guesswork. This is especially helpful when aligning templates over complex carved bodies or unusual pickups.
Frequently Asked Questions
- Are acrylic templates universal for all bass bodies? Not exactly. Many templates target standard Jazz, P, or Humbucker configurations. Verify cavity dimensions and radii match your specific bass model.
- Do these templates require special routers? They are designed to work with common routers and bits, but confirm that your bit diameter and router bearing align with the template’s cutouts.
- Can I reuse templates for multiple projects? Yes, the durable acrylic templates are reusable with proper care and cleaning between uses.
- Should I modify templates for unusual body shapes? If your bass body has non-standard contours, you may need a custom jig or a more adaptable template set.
- Is there a risk of misalignment when using multiple templates? Always clamp and align carefully. Use the template’s reference edges and mounting holes to minimize shift during routing.
- How do I verify correct cavity depth? The template’s specified thickness (commonly 9–10mm) helps set router depth; use a depth stop or test cut on scrap material first.
