THE BEAST

In a world filled with endlessly tweakable amp simulators, Bogren Digital has flipped the script — and Colin from the YouTube channel Science of Loud is here for it. In his recent video, “ONE Knob Marshall Tones? Bogren AmpKnob Makes Plug-ins EASY!” , Colin dives headfirst into the Bogren AmpKnob plugin suite, and what starts with skepticism quickly turns into genuine surprise.

From Amp Sim Cynic to Believer

Colin kicks off the video with a blunt confession: “I hate amp sims.” As a guitarist and tone enthusiast, he’s used to the feel, dynamics, and nuance of real amplifiers — especially Marshalls. But when he loads up the Bogren AmpKnob plugins, specifically designed to emulate classic Marshall tones, something changes.

Marshall-Inspired, No BS

At 0:33 , Colin introduces the AmpKnob plugin line, which includes a range of Marshall-style models, each dripping with that British midrange bite and growl. Whether you're chasing JCM800 crunch or Plexi swagger, the tones are unmistakably authentic.

The Magic of One Knob

The real kicker? There’s only one knob.

At 2:26 , Colin highlights the absurdly simple interface. Gain and volume in one control — that’s it. No convoluted EQ sections, no impulse response lists. Just raw, usable tone out of the box. This simplicity proves to be a game-changer, especially for players who just want to get to playing or recording without a science degree in digital gear.

Real Feel in a Plugin?

One of the biggest criticisms of amp sims has always been feel — that visceral interaction between player and amp. At 4:54 , Colin addresses this exact concern. Then, around 8:29 , he introduces IRDX technology , a proprietary feature in Bogren’s plugins that enhances the realism and dynamic response. And according to Colin, it works. The difference in how the plugin responds compared to others on the market is palpable.

Blown Away by the Tone

By 12:09 , Colin is putting the plugin head-to-head with a real Marshall amp. He’s shocked to find the plugin doesn’t just hold up — in some ways, it sounds better . The tightness, clarity, and warmth hit all the right notes, and the lack of setup hassle is a huge bonus.

Try It Yourself

At 13:24 , Colin wraps up by encouraging viewers to try the Bogren AmpKnob plugins for themselves. There’s a free trial available, and for players looking for no-nonsense tone with pro-level quality, it’s a must-try.

Final Thoughts

What started as a reluctant test turned into an enthusiastic endorsement. Bogren AmpKnob has taken all the best elements of analog tone, stripped away the unnecessary fluff, and delivered a plugin that just works .

And as Colin from Science of Loud proves — even the most stubborn tube amp purist can be converted with the right sound.
