Common Questions

Q: Which variant should I choose — PCB or Stainless Steel?

A: Both are accurate and functional. The PCB version is great for home use and occasional setups. The stainless steel version is more durable and better suited for frequent professional use or luthier work.

Q: What is the ideal string action for electric guitar?

A: A common starting point is 1.5–2.0mm on the high E string and 2.0–2.5mm on the low E string at the 12th fret. Preferences vary by playing style — lower action suits lead playing while higher action suits heavier strumming.

Q: Can I use this for bass guitar?

A: Yes — the ruler is compatible with all stringed instruments including bass guitar. The metric and imperial scales cover the measurement ranges used for bass setup.
