Frequently Asked Questions

Q: What is stylus overhang and why does it matter for LP vinyl playback?

A: Stylus overhang refers to the distance the stylus tip extends beyond the tonearm pivot point. Correct overhang alignment ensures the stylus tracks the record groove at the optimal angle, resulting in the best possible sound quality, reduced groove wear, and accurate stereo imaging. This cartridge alignment ruler helps you set that distance precisely using the SME-style 52mm reference.

Q: Is this tonearm alignment ruler compatible with my turntable?

A: Yes — this alignment ruler is designed to be compatible with most standard turntables that support 33 and 45 RPM playback. It works with a wide range of headshell and tonearm combinations, making it a versatile tool for both beginner and experienced vinyl enthusiasts.

Q: Can this ruler be used as a cartridge stand?

A: Absolutely. In addition to its alignment function, the ruler doubles as a small resting stand for your cartridge and headshell kits, keeping delicate stylus components safe while you work on your tonearm setup.

Q: How accurate is this alignment ruler?

A: The ruler provides clearly visible measurements with a 52mm SME-style reference distance. As with any manually produced tool, a tolerance of up to 5mm may exist. For critical audiophile setups, we recommend verifying measurements with a protractor as a secondary check.
