Peavey 5150

"Maybe the most well known amplifier released under the Peavey name, the 5150 is the result of a collaboration between Peavey and Eddie Van Halen. [...] It has become an industry standard for modern metal bands such as Chimaira, August Burns Red, All That Remains and others."

"You'll often hear [the 5150[] in heavy [music] genres like rock, metal and hardcore. The most influential example could be Machine Head's "Burn My Eyes" from 1994, which pretty much defines the mid-90s metal guitar sound."
