packs have been released since April 11, 2007. Additionally, two packs featuring new content to the Guitar Hero series have also been released, including songs from My Chemical Romance, Protest the Hero, Trivium, and Atreyu. There have also been individual track downloads featuring songs from bands Los Rodríguez, Pleymo, and Soilwork. Featured instruments Guitar Hero II features many popular real world Gibson, Epiphone, and Kramer guitars, including the Gibson Les Paul, Gibson SG, Gibson Flying V, (these three being the only ones available from the start) Gibson Sonex 180 and Gibson Explorer. Oddities such as the double necked Gibson EDS-1275 and unusual looking Gibson Corvus also make an appearance. Several available finishes are also recognizable from popular guitarists, including Zakk Wylde's bullseye Les Paul. As play progresses, several custom shaped guitars become available, although some are notable in the real world such as the US and Battle Axe (a similar looking bass is played by Gene Simmons, and the guitar was played by John Christ of Samhain/Danzig fame). Basses, such as the Music Man StingRay, Gibson Thunderbird, and the Höfner bass (as made famous by Paul McCartney, the bassist for the Beatles) are also available for co-op play. The band itself plays with Orange amps and DW drum kits, along with more in-game endorsements. When the player passes each set of songs in career mode, his/her band is rewarded with money and equipment endorsements, including Ernie Ball strings, Boss effects, Line 6 guitar amplifiers, VHT amplifiers, Mesa Boogie amplifiers, and Roland keyboards. These products then appear on stage while the band plays the ensuing setlists. Reception The PlayStation 2 version of Guitar Hero II was critically acclaimed.
