The width of the brush and softness that we are not afraid of scratching vinyl records. Really a great product that I recommend to all lovers of black music lovers patties.
Only (very) small problem: the width of the brush and velvet lining induces a higher frictional force than a carbon brush. We must therefore meter the force with which you press the disc when using (like me) this brush on the set in motion of its platinum, otherwise block the disc (which probably impacts the life of the engine torque / belt). Note that this applies in my case at a Pro-Ject Debut Carbon Esprit platinum, including acrylic tray is devoid of cover plate Felt. This phenomenon is perhaps less obvious on a classic board.
