Description of the OM Q.Bert from the official Ortofon website:
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.
The Q-Bert has a supreme ability to trace the grooves of your records and it is tailored specifically for scratch. Due to its enomous output, it is perfect for scratch of all music with deep bass frequences.
