Everything you need to know about .strandberg* zero-frets
All .strandberg* instruments come equipped with a zero-fret that substitutes a common nut as the first contact point between the strings and the neck. The advantages of utilizing a zero-fret in combination with a common nut for string guidance are the following:
- Complete sonic balance - Open and fretted notes will have equal sonic properties and character.
- Correct height of open strings - The use of a zero-fret of a calculated size ensures that the open strings reside on equal height above the fretboard as the strings do when they are fretted.
- Better tuning stability / better intonation - A minimal contact surface will ensure the least amount of friction and provide a more accurate intonation reference point.
The fretwire we use for this task is slightly taller (0,01"/0,25mm) than the remaining frets because this generally leads to better playability and ease of setup. Additionally, as most of our bridges are made from anodized aluminum that is not electrically conductive, the zero-fret connects all strings to ground through the G-string bridge ground (6-string) and A-string bridge ground (7- and 8-string).
The zero-frets on our guitars are made from the same supreme quality stainless steel as all the other frets and are capable of withstanding extended periods of use before needing service, but it may need slight touching up at one time or another on account of the pressure from the strings on a small contact surface. This is to be expected and we encourage all players not to be alarmed if one day encountering small scratches or dents as these are easily removed and the surface restored to its former glory. If you have a dent in your zero fret, please follow the steps below to have it removed quickly and easily. Note that you don't have to use the exact products and procedures that we're using. If you prefer another sanding- or polishing product, please use that instead and the same goes for the procedure itself. As with any maintenance work, there are several ways of performing it with satisfying results.
1. Remove the strings to reveal the problem areas.
2. Mask of the working area to avoid scratching the surrounding surfaces.
3. Use a small piece of fine-grit sanding paper as a first step in dent removal. 400-1200 grit is used in progressively finer steps for the best results and the least amount of excess wear. The grit starting point will be dependant on the severity of the dent(s). There are also various polishing pads available on the market that can be used instead of sanding paper if you so prefer.
4. Finish the fret of with fine 0000 steel wool to have a completely smooth surface with a high luster. If you prefer a polishing product other than steel wool, please use that instead.
5. You're done and the guitar is ready for restringing!
