The Fender Telecaster Thinline is a semi-hollow guitar made by the Fender company. It is a Telecaster with body cavities. Designed by German luthier Roger Rossmeisl in 1968, it was introduced in 1969 and updated in 1972 by replacing the standard Telecaster pickups with a pair of Fender Wide Range humbucking pickups, bullet truss-rod and 3-bolt neck. The design was originally an attempt to reduce the weight of the solid-body Telecaster guitar, which had become ever heavier throughout the 1960s due to the dwindling supply of the light ash wood Fender had formerly used. The f-hole and reshaped pickguard are the most apparent visual clues to its construction. There have been many different versions of the Telecaster Thinline over the years, although the original two are more recognizable. The 1969 version has two standard single-coil pickups and a mahogany body, while the 1972 version, based on the Fender Telecaster Deluxe, has two Fender Wide Range humbucking pickups and a natural swamp ash body. Thinline versions have been made in Mexico and Japan as a part of the Classic Series of guitars and basses, followed by higher-end American-made Factory Special Run (FSR) versions from the Fender Custom Shop in 2005 and 2013. A much lower price Thinline design was produced in China and featured P-90 pickups and a mahogany body. While it retained the "Fender Telecaster" name on the headstock, it was not labeled as a Thinline, although the F-hole design and hollow construction makes its heritage obvious. 1990s Telecaster Thinline This short-lived model was based on the '69 Telecaster Thinline, but used many of the modern features found on the first-generation American Standard Series guitars manufactured between 1986 and 2000. It was introduced in 1998 and discontinued at the beginning of the 21st century. 2004 FSR American Vintage Telecaster Thinline In 2004, a few thinlines were made for the Yamano company in Japan. These are all USA Fender models made in the Corona factory. Though they were built strictly for sale in Japan, some seemed to make it straight to the United States for sale. Fender Cabronita Thinline Telecaster For two years, 2012 and 2013, Fender offered the Cabronita model as a Thinline in Shoreline Gold and a swamp ash bodied white blonde model. These were built in their Ensenada, Mexico plant. Squier Thinline Telecasters Fender's subsidiary company Squier also makes entry level Thinline Telecasters. This includes the Master Series
