Lone Buck Guitars Bass Guitar Adjustable 30" - 34" Fan Fret Multi-scale layout tool for fingerboard fretting Acrylic 2025

This listing is for the Bass Guitar size 30" and 34" scale combination. See other listings for different size combinations along with bass sizes.

This is the new adjustable Fan Fret Multi-scale fretboard layout tool. I created this to make the tedious job of laying out a multi-scale fan fret on a fingerboard blank. This tool works by having two different scales set side by side with three brackets that allows you to slide the scales to the desired 'neutral' fret. Then simply tighten down the clamps, line the center of the tool on your fretboard blank and mark each side at the center of the outer string. Once marked, you just connect the marks with a straight edge and you are all set to cut. You can literally layout and mark a blank in under 10 minutes to the point of being ready to cut.

I made 4 scales for guitar 24, 24.75, 25 and 25.5", and 4 scales for bass 30, 32, 34, and 35". You can order any combination you want to make the scale combination you desire. Because the fret slots and markings are equally centered on each section, this can also be used to lay out a fan fret on a left handed guitar simply by changing the sides (long on bottom to short on top flipped to short on top to long on bottom.)

The tool is made from 4 mm cast clear acrylic and the brackets are connected with steel screws and brass thumb nuts. Frets are marked at 3, 5, 7, 9, 12, 15, 17, 19, 21 and 24th fret (for the longer scales). The marking slots are 2mm wide allowing for a mechanical pencil to reach down for marking. I have uploaded a few photos of part of a fretboard layout on a lighter piece of wood to show how it works.

Individual sides can be purchased separately to expand your multi-scale options. See individual listings for the main tool combinations and for the individual side options.
