Preparation and Safety Guidelines

Tools Needed
  • Chroma Cast Case
  • Exacto Knife
  • Styrofoam (Owens Corning Formula 250)
  • Jigsaw
  • Belt Sander (or Pringles can and sandpaper)
  • Sharpie
  • Faux Fur
  • 3M High-Strength 90 Contact Cement
  • Scissors
Safety Guidelines
  • Always prioritize functionality over aesthetics. Modifications that compromise the case's structural integrity (e.g., excessively weakening the shell) will leave your guitar vulnerable.
  • Use only high-quality, durable materials appropriate for the intended purpose (e.g., heavy-duty fabric, strong adhesives). Cheap materials can degrade quickly and fail to offer adequate protection.
  • If unsure about any step, consult a professional. Incorrect modifications can damage your guitar case beyond repair and potentially void any warranty.

  2. Create the Styrofoam Insert

    • Measure the internal dimensions of the case.
    • Cut a styrofoam insert slightly undersized (1/4 inch) to fit the body cavity. Round the corners to match the case.
    • Place the guitar in the case and trace its outline onto the styrofoam insert, adding at least 1/4 inch extra for fur coverage.
    • Cut out the traced shape, using a jigsaw for the main body and a belt sander (or alternative method) to shape the neck cutout.

Tips

  • Use an exacto knife to carefully slice around glued-on fur for easier removal.
  • Leave the bottom fur intact.
  • Use a jigsaw with an extra-long blade for cutting the styrofoam.
  • If you don't have a belt sander, use a Pringles can and sandpaper to carve out the neck area.
  • Work quickly but carefully with the contact cement, as it has a limited working time.

Common Mistakes to Avoid

1. Using Incorrect Adhesives

Reason: Using the wrong type of glue can lead to weak bonds that fail under pressure or create residue that damages the case material or your guitar finish.
Solution: Always use a strong, flexible adhesive specifically designed for use with the materials involved, and test it on a hidden area first.

2. Poorly Planned Modifications

Reason: Lack of planning and measurement can lead to misaligned parts, ill-fitting components and ultimately, a case that doesn't protect your guitar effectively.
Solution: Create detailed templates and measurements before making any cuts or applying adhesives to ensure accurate and secure fitting.

3. Ignoring Case Structural Integrity

Reason: Adding excessive weight or making structural changes without understanding the case's design may weaken it, reducing its protective capabilities.
Solution: Reinforce areas where significant modifications are made using supportive materials and ensure that any additions do not compromise the overall structural soundness of the case.

FAQs

What materials are best for customizing my guitar case?
Durable and lightweight materials are ideal. Consider using strong adhesives like epoxy, heavy-duty fabrics like canvas or ballistic nylon for exterior covering, and protective padding like closed-cell foam for the interior. For aesthetic enhancements, think about using paint (specifically formulated for plastics or wood), vinyl wraps, or even decorative hardware like rivets or buckles.
