Lathe cut records are made one-at-a-time, in real-time, by a real person. The sound is embossed on to the plexiglass, using an experimental process and a 70 year old machine.
Lathe cut records are NOT pressed records and may have slightly more surface noise (due to static build up and dust) or an occasional light distortion in some frequencies, but they sound pretty nice given the circumstances. The volume will be a little lower than a modern “post-loudness-war” record, so turn it up to enjoy. The records should track well, even on cheaper turntables, but if you have problems, adjust your tonearm weight and your anti-skate settings.
Lathe cut records will NOT degrade or harm your needle or cartridge.
