This is a list of heavy metal guitarists from the 1960s to the 2010s.
 Heavy metal guitar players use highly-amplified electric guitar playing that is rooted in the guitar playing styles developed in 1960s-era blues rock and psychedelic rock.
 Metal guitar playing uses a massive sound, characterized by highly amplified distortion, extended guitar solos and overall loudness.
 The electric guitar and the sonic power that it projects through amplification has historically been the key element in heavy metal.
Heavy metal bass is the use of the bass guitar (also called "electric bass") in the rock music genres of heavy metal and hard rock.
 The bassist is part of the rhythm section in a heavy metal band, along with the drummer, rhythm guitarist and, in some bands, a keyboard player.
 The prominent role of the bass is key to the metal sound, and the interplay of bass and distorted electric guitar is a central element of metal.
 The bass guitar provides the low-end sound crucial to making the music "heavy".
 The bass plays a "...more important role in heavy metal than in any other genre of rock."
