Precision fret fit: Addresses common fret problems including uneven crowns and burrs, enabling an optimal fit for acoustic models through bass-curve alignment for improved playability. Popular solution: Preferred by musicians to achieve smooth fretwire surfaces. Improves playing feel and tonal quality – a valuable tool for all string instrument fans. Enhanced playability: Multi-face grinding technique removes burrs efficiently, prevents oxidation, and increases intonation stability for a refined metal finish and optimal playing experience. Reliability: Gentle contact points and rigid construction support stable grinding with millimeter-precise accuracy, refined edge treatment, and careful results. Use scenarios: - Pre-setup fret work on acoustic guitars to improve action and intonation by ensuring a smooth, properly aligned fret surface. - Maintenance on electric guitars and basses to remove burrs, prevent oxidation, and achieve consistent edge quality across frets. - Professional luthier workflows for fret dressing and edge finishing to deliver precise, repeatable results on multiple instruments.
