Silver Dunlop action gauge with measuring marks around its edges.

When to choose it

Choose the DGT04 if you want both metric and standard markings in one compact setup tool. Read the edge that matches your setup notes and record the fret and string for the measurement.

The card can also help check pickup height. Use the instrument’s pickup procedure for that reading so you do not mix the pickup clearance with the action measured at a fret.
