Fits old Gibson, Lindy Fralin and many other reissue P90 dog ear pickups exactly.Manufactured in USA on Lindy's proprietary molds. Corner rounding and other features are as close to a '50s Gibson as I've ever seen. Bridge pickup cover overall height approx. .450". Neck pickup cover overall height approx. .335" on the high side tapering to .25" on the low side. As on the old Kalamazoo Gibsons the E to E pole spacing of 1.95" is the same for both neck and bridge covers. If you are in doubt about the Fralin covers fitting your specific guitar measure the pole spacing on your specific guitar prior to ordering. Be warned that many inexpensive "Epiphone" branded import guitars have narrower spacing P90 neck pickups that will not accept the Fralin cover.
