Manufactured in the United States, this straight edge can be used for any 24.75 or 25.5 scale instruments.  It's made from the strongest tempered aluminum we can find (6061-T65 tempered; may be scratched) and measures about 1.5" x 18.5" and is 1/8" thick aluminum. It has the 24.75 scale on one side and the 25.5 scale on the other side for Fender or Gibson style guitars. Can be used for 21-24 fret style necks as well. The 25.5 scale has 22 fret slots and the 24.75 scale has 23 fret slots. Both scales will fit if your instrument has more than 22 or 23 frets. It ships with reinforced packaging to prevent bending in shipment.  These are manufactured in North Carolina, USA.
