This premium JESCAR gold fret wire is absolutely beautiful, a perfect finishing touch for your special build or re-fretting job! It is gold all the way through, so it can be filed, crowned and otherwise dressed as much as necessary. It especially looks good on a darker fret board, so that the contrast is greater, but it also looks nice on lighter fret boards. This wire set comes in nine (9) 8" lengths, pre-radiused on a ~10.5" radius basis, which will help keep those ends down when you are installing it. It is somewhat harder than standard 18% nickel-silver fret wire, so it will last longer too! The size of this wire has a very wide crown with medium height, which makes it perfect for acoustic guitars and electric guitars. See the exact size specifications below. This wire will fit nicely into a .023" fret slot, which is pretty much the standard for most modern fret wires. We also include a 2-page sheet of fretting "do's and don'ts" to help the first-time fretter get started, at no extra charge! This fret wire is intended for bass guitars, electric guitars and any other instrument where you want the highest and widest fretwire for a scalloped fretboard feel. The 8-inch lengths allow you to easily cut the exact lengths you need. Technical Specs: Crown Height: .047" (1.19mm) Crown Width: .104" (2.64mm) Tang Depth: .061" (1.55mm) A slot width of .023" is recommended for this fret wire, but somewhat wider may work if you use glue to set the frets in. Be sure to measure the width, height and tang depth/width of your current frets before buying, to make sure this set will fit your intended usage! * Please note that tolerance on fret wire piece length is +/- 1/8" (.125").
