Designed for nut and saddle adjustment, bridge and neck leveling, and surface protection during routing or clamping. Useful for electric guitars, acoustic guitars, and basses. Key benefits Accurate height adjustment: use thin shims to fine tune nut and saddle heights without irreversible filing or shaving. Protects instrument finish: protective shims shield the body and bridge areas while clamping, routing, or levering. Versatile compatibility: fits most electric and acoustic guitars and basses for a wide range of and setup tasks. Easy to use: insert, stack, or trim shims to achieve the desired thickness; no special tools required for basic placement. Durable materials: a mix of thin metal and plastic shims provides stable, repeatable results and resists deformation during use. Features and attributes Function: leveling, spacing, shimming, and protective surface cover for setup, , and modification work. Compatibility: suitable for nut and saddle adjustment, bridge shimming, neck leveling, and protection during fretwork on electric and acoustic guitars and basses. Sizes: assortment of thin pieces in multiple thicknesses and lengths to address small incremental adjustments and larger spacing needs. Materials: combination of metal shims for stability and plastic shims for nonmarring protection and ease of trimming. Performance: holds position under light to moderate pressure, allows precise incremental changes, and minimizes the need for irreversible material removal. Practical applications Nut slot adjustment: add thin shims beneath a nut to raise its height slightly when action at the first fret is too low, avoiding immediate filing. Saddle and bridge shimming: stack or trim shims under a saddle to correct string height across the fretboard for better playability and intonation. and maintenance protection: place protective shims between clamps and the guitar body or neck during gluing, routing, or fret leveling to prevent dents and finish damage. Usage tips Start with the thinnest shim and increase thickness in small increments until the desired action or clearance is achieved. Trim shims with a hobby knife or fine snips and smooth edges before installation. Test string action and playability after each change to avoid overcorrection. This shim set provides a simple, reliable way to make reversible adjustments and protect your instrument during setup and tasks.
