BassKnob Trivium: Bass Amp Simulator Plugin by Bogren Digital

The Green Boost gives a clean, sparkly tone that can be pushed to the edge of breakup, and this mode also includes a lush reverb. Orange Boost starts at crunch and can produce a distinctive, heavy distortion when the gain is raised. Red Boost is aimed at a high-octane tone with a lot of clarity for fast picking.

The rhythm amp comes with two cabinets, Modern and Vintage, which the developer says were captured at Fascination Street Studios. A Drive button adds overdrive when the amp sounds too clean. The developer also notes that the cabinet can be disabled or replaced with a custom impulse response.

Bogren Digital's IRDX (Impulse Response Dynamix) technology adds dynamic speaker behavior to static impulse responses. According to the developer, IRDX uses machine learning to reconstruct the difference between a real cabinet and an impulse response, so the speaker responds to playing dynamics.

The developer describes the result as an amp simulation that reacts more like a real amp and sits in a mix without sounding static or fatiguing.
