Ortofon Replacement Stylus for Stylus GT

GT Replacement stylus for tough handling - extremely sturdy for scratching DJs

GT was developed by Ortofon in close co-operation with SWS Audio GmbH. The cartridge was named 'Great and Tough' and was based on the construction of the well-known Ortofon Series 500 design - mend for standard half inch mounting - in a black housing with white printing.

The vital parts in the GT are based on a very robust and reliable parts used in Scratch. Further, during development of GT, efforts were also concentrated on supplying a very high output of 8 mV and improvement of frequency response to give higher resolution and sound image.

Tracking avility is decisive for the DJs especially when scratching and back-cuing. In this situation raise of tracking force could be an immediate, but in many cases not very effective solution. The reason is that the antiskating adjustment, if not at a very moderate level, will double the skating effect when back-cuing.
