1. California police code used to denote an escaped criminally insane person.

2. An album that hit in 1986 by Van Halen. It's the first album by the "Van Hagar" lineup. Also, the album's name comes from the studio it (and 1984) were recorded.

1. Positive. This is Sgt. Pepper reporting a pursuit of a 5150. Do you copy?

2. This is dialog from a VH concert I went to.

Sammy Hagar: And just does "5150" mean?

Mike Anthony: It means that you're a crazy motherfucker!

Crowd erupts in cheers.

The Peavey 5150 Amplifier was an all-tube guitar amplifier made by Peavey Electronics from 1991-present, that was made as a signature model for Edward Van Halen. The amp series was designed by a partnership of Peavey Engineers and Edward Van Halen. The 5150 was originally designed to achieve Van Halen's lead tones; however, due to the amp series' power, flexible equalizer, extreme hi-gain capabilities, and retention of articulate tonal definition at extremely high volumes, the amp series became the standard for modern hi-gain metal tone. Since Edward Van Halen and Peavey parted ways, in 2004 the name of the Peavey model was changed to 6505, with Van Halen taking the 5150 name for his company, EVH, to name his 5150III amplifier.

A lot of bands use the 5150 for studio and live preformances.
It is to be considered one of the most widely used valve top in metal/rock gernes.
