single-coil tone when split by the rotary switch. PRS developed pickups for the aggressive rock market, offering pick ups such as the chainsaw, and the Hot-Fat-Screams (HFS) initially used on the Special model. In 1998, an electronic upgrade kit was released for pre-1993 instruments which included lighter-weight tuner buttons, nickel-plated brass screws for saddles and intonation, a simulated tone control, and high-capacitance hookup wire. In 2012, PRS released the 408 pickups used on the 408 and Paul's Guitar models. These pickups include innovations that feature no loss of volume when in coil split mode. They have an exclusive agreement to use wire drawn from the same machine that made wire for Les Paul and Stratocaster pickups in the 1950s. Certain models of PRS Guitars have also used pickups by Lindy Fralin, notably in the EG II and certain specs of the Custom 22. Models In 1985, Paul Reed Smith started producing factory made guitars, which later became known as PRS Standard. In 1988, Paul Reed Smith introduced its more affordable Bolt-On series known as classic electric (CE models) which were discontinued in 2009. In 2016, the CE line was put back in production. In 1990, PRS EG was introduced as company's first 22-fret guitar. Later on in the more successful 1992 PRS EG II was introduced, which includes PRS's first left-handed guitar. In 1992, PRS introduced the Dragon 1 model. Only 50 units were produced. It featured an intricate dragon inlay which ran down the finger board, a wide 22 fret neck, a non-vibrato Stop-tail bridge, and a new pick up design. The changes in design from previous models added a noticeable tonal improvement which led the company to use the same characteristics in later models such as the PRS Custom 22. The Dragon 2 was released in 1993, and the Dragon 3 in 1994. Both featured dragon inlays which became more extreme with every year. Only 100 of each of the 2 models were made. In 1999, PRS released the Dragon 2000, which featured complex body curves, and a 3 dimensional dragon inlay. Just 50 Dragon 2000's were ever produced. In 1994, Paul Reed Smith collaborated with Ted McCarty and launched the "McCarty" Series. The McCarty series offers a more vintage feeling and sounding PRS Guitar. PRS introduced a more affordable line of guitars in 2000 referred to as the "SE" which are manufactured in Korea by World Musical
