Every guitar we sell comes with our complementary Guitar Enhancement Package. The complete package includes: Fret polishing with 6000 to 12,000 grit micromesh. Any fret oxidation is removed during this process. Guitar wiped down to get rid of any excess buffing material. Action optimized and lowered. Pickup height adjusted for optimal clarity. This is somewhat subjective but we feel the majority of guitars we receive can use a slight tweak. Proprietary anti-corrosion treatment applied for all hardware. On hardtail guitars the nut will be lubricated prior to shipping out for enhanced tuning stability. On trem equipped guitars, the knife edges will be lubricated to ensure they are ultra-stable. Guitars are repolished and buffed. Electronics are cleaned with contact cleaner. This is usually not necessary but just something we feel takes things to the next level. Trem equipped guitars also have their springs stretched.
