Kluson Telecaster Control Plate. Fits USA spec Tele®. Also fits most MIM and Japan made Telecasters.
I normally keep away from Tele Control Plates because there are so many cheap import Plates being offered for sale and the specs are all wrong, 95% of them won’t fit a USA Fender Telecaster. These Kluson ones have been copied from a genuine USA Fender Telecaster Control Plate, but they have one huge advantage over the Fender Plate, by my request, Kluson lengthened the slot slightly for the switch lever, which now lets you use the Oak Grigsby 4-way switch without issues that the 4-way is notorious for.
The Oak Grigsby 4-way switch lever needs slightly more travel compared to the CRL 3-way and 5-way switches and most times the switch lever hits the end of the control plate slot before it engages fully into position 1 or position 4. Before these Klusons came out, it was a case of filing both ends of the slot with a diamond needle file, or alternatively filing the switch lever width.
