Frequently Asked Questions

Q: What is a turntable cartridge alignment ruler used for?

A: A cartridge alignment ruler (also called a stylus overhang gauge) is used to precisely position your turntable cartridge in the headshell. Correct alignment ensures the stylus tracks record grooves accurately, improving sound quality and reducing wear on your vinyl records. This SME-style ruler measures the critical 52mm distance from the stylus tip to the tonearm pivot point.

Q: Is this alignment ruler compatible with my turntable?

A: This ruler is designed to be compatible with most standard turntables that use SME-style tonearm geometry, supporting 33 RPM and 45 RPM setups. It works with headshell and bracket-style tonearm assemblies. If you are unsure of your tonearm type, please check your turntable's manual or specifications before purchasing.

Q: Can I use this as a cartridge holder while installing?

A: Yes! One of its handy dual-purpose features is that it also acts as a small stand to rest your cartridge kit on while you perform adjustments — keeping components stable and within reach during the alignment process.

Q: What material is the alignment ruler made from?

A: The ruler is made from lightweight, durable plastic, keeping it compact and easy to handle. Its small size (approx. 3 × 6.5 cm) makes it easy to store with your other turntable accessories.
