ESP Jeff Hanneman is an electric guitar model distributed by ESP for the late Jeff Hanneman of the thrash metal band Slayer. Despite it being his signature guitar, the instrument is not exactly to the original specifications. Hanneman's own instruments (all modeled after his favorite Jackson Soloist - the guitar used on most of Slayer's albums) have pure maple, not alder, bodies. The ESP edition originally featured a Floyd Rose tremolo, which upset a large number of Slayer fans. In response, ESP began offering the Kahler 2315.
