Ortofon Pro Stylus

General purpose model for scratch and back-cueing

Great performance and durability as to basic scratch and back-cueing is what the Pro is known for. It has a good quality spherical stylus, a rock-solid cantilever, and serves general purposes well.

The Pro is the logical alternative to the more expensive expert carts. It offers both reasonable output and high sound quality which is, in fact, all there is needed to entertain an audience.

The Pro Series of cartridges provides a great balance of sound quality with tracking ability, for virtually any style of music.
