Get the AmpKnob BH4 Black Friday deal at $24.50, 50% off, with the offer ending Nov 30, 2026: Bogren Digital's high-gain amp simulator plugin, built around two mix-ready channels.
The AmpKnob BH4 is an amp sim for guitar that runs inside your DAW and as a standalone app. The maker says it is based on an amp known for staying clear under high-gain pressure.
The plugin features two channels, 3 and 4. Producer Jens Bogren oversaw the capture of both, and the maker describes them as mix-ready.
A finely tuned boost pedal option sits in front of the amp.
Bogren Digital says the two channels give the tone real thickness.
You choose between a Modern cab and a Vintage cab, or you load your own IR.
The cabinet section runs on Bogren Digital's IRDX technology. AmpKnob BH4 gives the bundled cabinet simulations a lifelike, playing-sensitive feel.
IRDX also applies to any cabinet IR you load into the plugin. The maker says those IRs respond more dynamically than they do in a standard IR loader.
The standalone version lets you start playing without launching your DAW. That suits practice sessions and quick riff ideas.
It includes a metronome and a riff recorder.
When a riff works out, record it on the spot. Then drag the sound file into your DAW and build the rest of the track around it.
The riff recorder pairs with the built-in metronome for practice runs.
Both the plugin and the standalone version include:
Like the rest of Bogren Digital's Ampknob series, the BH4 is built to be easy to use. Bogren Digital describes it as a distraction-free route to album-ready sounds.
Jens Bogren has put more than 20 years of experience into the sounds, so you can concentrate on the music rather than on menus.
Yes. The AmpKnob BH4 Black Friday deal takes 50% off, bringing Bogren Digital's amp simulator plugin to $24.50. The offer ends Nov 30, 2026.
You get two amp channels (3 and 4), a boost pedal option, Modern and Vintage cabs with custom IR loading, and IRDX cabinet response. Both versions also include a tuner and a noise gate.
Yes. It comes in standalone versions alongside the DAW plugin. The standalone app adds a metronome and a riff recorder, so you can practise or capture ideas without opening your DAW.
Yes. Besides the Modern and Vintage cabs, you can load your own IR. Bogren Digital says its IRDX technology also applies to any cabinet IR you load, giving it a more dynamic response.
