some common string widths and curvatures

4 String Bass Pickups

The most common string width (center of low string to center of high string) for these is known as

"Fender width" - 3/4" per string / 2-1/4" total

or 57mm total string width at the bridge.

5 String Bass Pickups

From the beginning these instruments were made in a wide range of string widths.

The most common widths are:

66mm,

70-72mm and

76mm total string width at the bridge.

6 String Bass Pickups

From the beginning these instruments were made in a wide range of string widths.

The most common widths now are:

82mm,

86mm,

92mm and

96mm total string width at the bridge.

7 String Bass Pickups

These instruments are just establishing themselves. We make pickups for many instruments being built with 103 - 108mm total string width at the bridge.

Fingerboard Curvature

In general, modern instruments have lower fingerboard curvature than earlier ones. Fingerboard curvatures fall into three categories: "nearly flat" (meaning 14" radius or larger), "Gibson-like" (meaning approximately 12" radius) and "Fender-like" (meaning early Fender, approximately 10" radius).
