What does the CheckCard help you check?
It allows fast verification of critical setup values such as string height references, fretboard geometry consistency, and general setup accuracy.
How is the CheckCard different from feeler gauges?

Why are fret-shaped gauges easier to read than standard string action gauges?
The fret-shaped gauges profile aligns more naturally with the human eye, making reference points easier to interpret visually compared to flat or generic string action gauges.
When should I use the CheckCard?

Who is the CheckCard designed for?
