The string action ruler (also called string action gauge) is a pocket sized metallic ruler that is used to measure various guitar and string settings for optimum guitar setup and playability! It’s the perfect tool for setting up your guitar to meet your own personal requirements. It can also be used for other stringed instruments.
The ruler is made of durable stainless steel. Measurements are in metric and imperial units.
Dimensions: 3.5″ x 2″
Both sides are used for making different measurements
Side A (logo side)
- String Height Measurement Scale (top = mm, bottom = inches)
- Measurement scale for saddles, pickup pole pieces (pickup screws) and nuts (right = mm, left = inches)
- Bridge Saddle Slot and fret slot depth measurement scale (right = mm, left = inches)
- String Action Setup measurement guide (center grid)
- Strong, bridge sadlles and nut string spacing measurement scale (top: 75mm)
- String, bridge saddles and nut string spacing measurement scale (bottom: 3 inches)
- String heigth/action measurement: slide the string action ruler flat on along the first or sixth string to the 12th fret in order to measure the string action. Refer to the Side B central table for optimum string action measurement. If your particular guitar has an adjustable bridge and/or saddles you will be able to lower or raise the heigth to your particular liking.
- Saddles, pickup pole pieces and nut measurement
- Use this side to measure your saddle or tuhumb wheel height before removing your bridge in order to keep the same height when replacing the bridge
- Use this side to measure the distance between your pole pieces and the strings (usually 2-3mm but can vary)
- Use this side to measure your nut height whilst doing advanced setups
- Insert into the bridge saddle slot or fret slots to check alignment and depth
- The string action guide in the center displays themost common string action settings, depending on the type of guitar you own.
- Use the string, bridge saddle and nut string spacing measurement scale to measure the distance between the bridge saddles and the nut string grooves.
