Info & Manuals
The ARP 2600 is a semi-modular analog subtractive audio synthesizer, designed by Alan R. Pearlman with Dennis Colin, and manufactured by his company, ARP Instruments, Inc. as the follow-on version of the ARP 2500.
ARP's 2600 is without a doubt one of the finest analog synthesizers ever produced. For decades, it has been used in all forms of music and in the hands of many famous artists. This unique semi-modular monophonic synthesizer was designed for professionals but was also user-friendly enough to be used as a teaching instrument. The 2600, in fact ARP as a whole, competed directly against the synthesizer systems coming from Moog throughout the 1970's. The 2600 was ARP's answer to the modular system, creating a more compact, more stable and more intuitive synthesizer.
It was released in 1971, and continued until the manufacturer ceased operations in 1981 and used by many famous artists such as Pete Townsend (The Who), Ozzy Osbourne (Black Sabbath), John Lennon, Jimmy Page (Led Zeppelin), Pink Floyd, Giorgio Moroder, Kraftwerk, Daniel Miller (the Normal/Mute Rec), Vince Clarke (Depeche Mode), Beastie Boys, Rick Smith (Underworld), Chemical Brothers, Marilyn Manson, Matthew Bellamy (Muse) and Soulwax/TooManyDj's.
