The Ampknob BH4 plugin captures the unmistakable authority of a modern high-gain classic; an amp built for absolute tightness, surgical detail, and unwavering control under extreme distortion. Its focused midrange and firm low end have made it a defining tool in contemporary metal production.

Inside Fascination Street Studios, this amp holds a distinct place in Jens Bogren’s workflow. It’s the unit he often reaches for when a mix needs a rhythm tone that stays locked, steady, and readable no matter how dense the arrangement becomes.

When Jens needs a guitar tone that refuses to fall apart, the BH4 is one of the first amps he turns to.

Legendary channels 3 & 4

The BH4 is one of the most respected high-gain amplifiers in modern metal.

Channels 3 and 4 deliver exceptional thickness and clarity and remain stable even under the most aggressive riffing.

Two cabs

Included are two perfectly matched cabs, Modern and Vintage, giving you instant mix-ready tone without compromise.

You also get the option of loading up your favorite IR from the Bogren IR packs or any other IR of your choice.
