I purchased a box full of old guitar pickups from a music store that went out of business several years ago. The store opened in the early 1950's, so most of the stuff in the box was vintage. One of the sound hole pickups in the box is labeled "TP MELODY MIKE PAT. PENDING" on the black plastic pickup cover and "AUDIO EQUIPMENT CO. INC. GREAT NECK, N.Y. U.S.A." on the ON/OFF volume control piece. I can't find any information on this pickup. Anybody heard of this brand?
