the Fender Eighty-Five and the Studio 10. They contain the same 65W RMS circuit, but contain a 12" speaker and a 10" speaker, respectively. The Fender Eighty-Five was used by Steve Miller (Steve Miller Band) and Jonny Greenwood (Radiohead) on many recordings. The 21st Century: reissues and modeling In the first fifth of the 21st Century, Fender turned to digital technology to expand its lineup of amplifiers. The first of these, the Cyber Twin and Cyber Deluxe, used circuits within the computer chips to replicate famous amps and effects. The preamp is tube-driven, and the power amp is solid state. Next came the G-DEC (Guitar Digital Entertainment Center), a true modeling amp. It was released in 2007 along with a PC software package to allow it to emulate a wide array of pedals, stompboxes, and amplifiers. The G-Dec won high praise at the time but its effects, based on three-decade-old MIDI technology, were rapidly outdated. An updated G-DEC 3 was released in 2010, followed by the Mustang in 2012. 2014 saw the traditionally-styled Champion amplifier (not to be confused with the classic and reissue Champion/Champ tube amplifiers) released. This amp eschewed the Fuse software in favor of an on-board system, selected by knobs. 2015 saw the release of the Mustang v.2 amplifiers, along with a refresh of the Fuse PC app. In 2017, the Mustang GT series was launched, with Bluetooth capability and wi-fi for over-the-air software updates, with a modernized look and smartphone-enabled functionality through the new Fender Tone app. At the same time, Fender re-released a number of classic amplifiers such as the Bassman and Bandmaster, to high praise both from the music press and the public.
