NOTE: Because this needle is designed for use specifically with Pickering cartridges, it can be found in numerous brands of turntables. In some cases the cartridges for this needle may be original equipment supplied with a new turntable, but was more likely selected at time of sale to complete a turntable sold without a cartridge or later as an upgrade to the original cartridge supplied by the turntable manufacturer. This needle should be matched primarily to the cartridge type not necessarily the turntable.
