Floyd Rose SpeedLoader is a floating guitar bridge based on the Floyd Rose Original. In development since 1991, it was introduced to the public in 2003. This tremolo was developed in San Diego CA at AJ manufacturing by tool makers Jerry Morhman, Richard J Price, Steve Lamms, and Kerry L Stottlemyer under the direct guidance of Floyd Rose himself. With Richard J Price doing the majority of the design work and machining of the prototypes. Over 3000 hours and $150,000 were spent in developing this new ground breaking tremolo system and the first working unit on a guitar body. It inherited the locking floating bridge principle from the original version, but improved usability and diminished most of disadvantages that the Floyd Rose Original was criticized for, while adding the inconvenience of needing special-purpose strings. The Floyd Rose SpeedLoader is available in Tremolo, Fixed Bridge, and Convergent Tuning forms. == Differences from the Floyd Rose Original == The SpeedLoader bridges differ from the original 1977 bridges in that the procedure for changing strings has been made easier. The original string replacement procedure involved cutting the ball-end from a new guitar string, "locking" the freshly cut end into the bridge using an Allen wrench, winding and rough tuning the string by using the machine heads, locking the string at the nut (the second lock of the double-locking system), and finally tuning it utilizing the fine tuners. When old strings are replaced with new strings, the tension provided on the floating bridge becomes slightly different, meaning that adjusting the tuning of one string with its machine head will undoubtedly alter the tuning of the other strings. During the process of rough tuning a Floyd Rose equipped guitar, the locking nut is usually left unlocked throughout the entire string replacement procedure, which facilitates adjusting the tuning of all the strings using the machine heads. However, the SpeedLoader bridge utilizes specially manufactured strings. The strings are pre-cut to a very precise length (to sound very close to the right pitch when installed) and have special ends which snap into the bridge and nut. Once the replacement strings are in place, fine-tuning is performed in a fashion similar to the Floyd Rose Original bridge. The process for changing strings is simpler and faster; trained guitar technicians are able to change all 6 strings in under 30 seconds. Consequently, guitars with Floyd Rose SpeedLoader bridges don't need any machine heads at all. For example, Floyd Rose Redmond series guitars come with a purely decorative headstock - unlike, for example, the Steinberger instruments without any visible headstock. As with any guitar, ambient temperature, humidity, and string wear can affect the tuning. If the fine tuners alone are not enough to tune guitar properly, the SpeedLoader bridge has ''range tuning screws'', one for each string, that control the range of each fine tuner's action. Like the original Floyd Rose bridge, the SpeedLoader bridge is a truly "floating" bridge and has some of the same disadvantages associated with it. Often, to alleviate these disadvantages, Floyd Rose Original owners utilize a custom mechanism called a ''tremstopper'' that is able to lock the floating tremolo fully (or partially) and make it behave like a fixed bridge. The Floyd Rose SpeedLoader Tremolo includes a built-in tremstopper. Finally, according to multiple interviews, Floyd Rose Guitars would not license manufacturing of these bridges to third-party vendors, as previous experience with Floyd Rose Licensed bridges showed that such "licensed" bridges can't match original standards of quality. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Floyd Rose SpeedLoader」の詳細全文を読む スポンサード リンク
