What AmpKnob BH4 does
Two channels are offered, which the developer describes as tone, thickness and clarity drawn from the BH4 amplifier the plugin is based on. The developer credits Jens Bogren, a master producer with more than 20 years of experience, with shaping the mix-ready character of the channels.
The cabinet section is powered by Bogren Digital’s IRDX technology, which the developer says applies to any cabinet impulse response loaded into the plugin. The standalone version includes a metronome, a riff recorder, a tuner and a noise gate, so the amp can be played without opening a DAW.
