Deco Gear 12" x 2mm Turntable Strobe Disc Stroboscope Mat

Dial in your deck for true, pitch-perfect playback. This Acrylic Turntable Strobe Disc (Stroboscope Mat) lets you check platter speed at a glance and fine-tune your turntable to exact 33/45/78 RPM under 50/60 Hz light. One side features high-contrast strobe rings for instant speed verification; the other adds a precise cartridge alignment grid to set overhang and offset. Rigid 12" acrylic stays flat and non-slip, so setup is quick, repeatable, and safe for your records—on any brand of vinyl player.
