What is a Dubplate?
A dubplate is a unique vinyl record used by DJs and music producers featuring custom recordings, exclusive tracks, or remixes that are not available to the public. Dubplates allow DJs to create unique performances with one-of-a-kind material, often rooted in reggae and dancehall music.
Modern lathe cut dubplates are produced using a lathe cutting machine, allowing for real-time audio cutting onto a disc. These records are often made from PETG (Polyethylene Terephthalate Glycol), offering durability and excellent sound quality.
