Co-developed by one of the most legendary DJs of all time, the Ortofon Q.Bert provides unsurpassed handling, high output voltage, and low wear characteristics that literally put it in a class of its own. Turntablists and mix DJs alike will appreciate the strong output of this cartridge, coupled with unrivaled tracking ability and sonic characteristics.  The Q.Bert features a more subdued high end, which helps to minimize surface noise from worn vinyl, and an accentuated mid-range to help bring scratching to the front of the sound stage.
