Bogren Digital AmpKnob BH4

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.
