The Coated Bottom Banjo Head has the traditional white look with a similar sound to a coated top head but puts the coating on the underside of the head because the smooth top surface is preferred by tenor and plectrum banjoists so it is quieter when strumming. Remo Banjo Heads are trusted by every major banjo manufacturer worldwide due to their quality of construction sound and performance. Sizes are available in 1/16 increments from 10 to 12 1/8 diameters. They come in three collar heights: Low Collar - 3/8 Medium Collar - 7/16 and High Collar - 1/2 .
