Three Signature Amp Models

Duo Rect
Inspired by the famed American-metal tone of the ’90s (like the Mesa Boogie Dual Rectifier)
With the iconic metal front panel that reminds you of countless classic records, from metal to punk to grunge, including Metallica, Tool, Korn, Soundgarden, Foo Fighters and Blink 182.

Fireman
Based on the British-voiced Friedman BE-100 for vintage and modern rock crunch that cuts through the mix.
The amp behind the signature tones of rock icons including Eddie Van Halen, Steve Stevens, and Jerry Cantrell.

VH4
Modeled after the iconic Diezel VH4 for thick, articulate, modern-metal tones with punch and clarity.
It has a thick, articulate and “meaty” sound, that is loved by many players and is used in many recording studios all over the world.
