Remo Inc. is an American musical instruments manufacturing company based in Valencia, California, and founded by Remo Belli in 1957. Products manufactured include drum kits, drumheads, drums, and hardware. History Drummer and founder Remo D. Belli experimented with PET film as a possible material for the production of drumheads after World War II due to its consistency in tonal qualities and resistance to weather changes. Throughout the 1960s, it was a fight to gain market acceptance, as purist jazzmen preferred the sound of natural calfskin. However, these calfskin drumheads had to be frequently tuned with weather fluctuations. Remo Belli created convenience for professional drummers when he pioneered the use of Mylar, a synthetic polyester film for drumheads. Originally, the drumheads were white and opaque to help mimic the look of calfskin. Later innovations were clear drumheads, two-ply drumheads (for added durability and depth), and simulated natural drumheads with a product called "FIBERSKYN", which is currently on its third version. Remo Belli died on April 25, 2016. Drumheads Remo supplies drumheads for various drum companies including Pearl, DW Drums, Yamaha, Mapex, Pork Pie Percussion, Tama drums, Ludwig drums, Gretsch Drums and Sonor. Remo has factories in the US and in Taiwan, where the "UT" and "US" versions are made. Ambassador / Vintage A / Ambassador X – A single-ply drumhead made from 10 mil of Mylar film.
