Our innovative and proprietary String Spacing Guide allows you to easily measure the string spacing of a bass whose measurements you wish for us to match. The front of the card displays three different nut spacings: 9mm, 9.5mm, 10mm, and the back of the card displays four different bridge spacings: 16mm, 17mm, 18mm, 19mm. Simply slide the card under the strings and butt the edge to the nut. Align the increment marks under the strings and identify which of the three spacing options best matches your string spacing. Repeat this process to identify the string spacing at the bridge, using the reverse side of the card.
