The Fender Twin is a guitar amplifier made by Fender. It was introduced in 1952, two years before Fender began selling electric guitars. The amps are known for their characteristically clean tone.
The Twin has seen a number of revisions since its introduction, both internal and external, with its designs sometimes varying greatly from one year to the next. Several variations on the amp's original design have been produced through the years, including the Twin Reverb, the Super Twin, the Twin Reverb II, and the Twin Reverb '65 Reissue. The Cyber Twin, which combined a tube amp with a computerized processor, was introduced in January 2001.
Many notable musicians have used Fender Twin amplifiers, including David Gilmour, Chuck Berry, The Beatles (1968 Twin Reverb amps using the AC568 circuit),Jimi Hendrix,Eric Clapton,Keith Richards from the Rolling Stones, Steve Jones from Sex Pistols, Jerry Garcia and Eric Johnson.
The Fender Twin has gone through a number of changes over the years, both cosmetically and electronically.
The original version was an all-tube combo amplifier with dual 12" speakers and two 6L6 tubes for a rated output of 25 watts.
After the preceding looks of the early 50's (TV front from 1950 to 51/2; wide panel '52–54), Leo Fender changed the cabinet design again, this time opting for no extra wood on the front of the amp, except for the narrow top and bottom panels that hold the baffle board to the cabinet.
