These EM2 pickup rings are modified for use with any TV Jones pickups with a universal mount. They fit the Filter'Tron pickup footprint. Make it easier to upgrade to TV Jones pickups with these easy-to-install rings, rather than worrying about exactly which pickup mount to use.
Please note: if installing on a Gretsch 5120/5122, ring risers are needed due to the higher neck angle of the guitar (2 for the bridge and 1 for the neck). Will also work with TV Jones English Mount pickups. These rings are sold individually, not in a pair.
