At the 2016 NAMM Show, VinylRecorder.com was demonstrating their DIY vinyl record cutting system.
This video, from the NAMM Show floor, Wesley Wolfe demonstrates how their system works.
The Vinyl Recorder T560 is a stereo vinyl cutter that works with a standard turntable. The system lets you do one-off and short runs of vinyl LPs.
