For Almost 30 Years, the Geo-Disc has Been the Most Accurate and Most Affordable Alignment Gauge!
The MFSL GEO-DISC makes cartridge setup easy! You will never realize the full potential of your cartridge without setting it up properly, but let's face it... mounting and aligning a phono cartridge can be a tedious and time-consuming chore. Not so with the Mobile Fidelity Sound Lab GEO-DISC!
Finally available again after too long an absence, the GEO-DISC is easy to use and extremely accurate cartridge alignment device. Simply put the MFSL GEO-DISC on your platter as you would a record and align your cartridge using the simple printed graph based on the Baerwald alignment curve. It's that easy!
