Metallica guitarist Kirk Hammett has teamed with Randall Amplifiers to help design a line of signature products including amps, heads, combos and preamp modules.

"Old-school tones and new-school technology attracted me to the potential
that Randall amps have to offer," said Hammett in a statement.

Hammett is currently recording Metallica's ninth studio album which is expected to be released next year. The Rick Rubin produced album and will be the bands' first release since St. Anger in 2003.
