Two Notes

Two Notes Audio Engineering is a French pro audio company that pioneered the concept of the digital reactive load box in 2008 — a category that has since become one of the most important developments in guitar and bass recording technology. The founding insight was straightforward but technically ambitious: give players a way to run their tube amplifiers at full power and full tonal character, capture that sound with studio-grade cabinet simulation, and deliver it silently to a recording interface or PA system without a microphone, a speaker cabinet, or a treated room. That idea, introduced through the Torpedo series, changed the way a significant portion of the guitar recording world approaches the studio. The technical foundation of Two Notes' approach is their DynIR technology — a proprietary cabinet simulation engine that goes considerably further than standard IR loading. Rather than offering a fixed snapshot of a cabinet's response, each DynIR capture gives the user eight microphone options, dual miking capability, and up to ten thousand mic positions, giving engineers and players the kind of real-time control over cab and mic placement that would normally require physically moving hardware in a studio setting. The library currently spans over 700 virtual cabinets including official captures made in collaboration with Mesa Engineering, Celestion, ENGL, Victory Amplification, and REVV — brand-authorized captures rather than third-party approximations. The product lineup covers the full range of how guitarists and bassists work. The Torpedo Captor and Captor X serve as reactive load boxes and attenuators for players who want to use their real tube amps at manageable volumes, with DynIR cab simulation built in. The ReVolt series offers three-channel all-analog amp simulation with a real 12AX7 tube running at 200V for players who want tube warmth in a pedalboard format without carrying a full amplifier. OPUS delivers full amp modeling and cabinet simulation in a compact floor unit, while GENOME — the brand's software ecosystem — brings the entire Two Notes toolset into the DAW as a complete virtual guitar rig with amplifiers, pedals, studio effects, and DynIR cabinets in a single plugin environment. At Wired Tunes, we carry Two Notes gear for guitarists and bassists who want authentic tube amp character in their recordings and live rigs — whether that means running a real amp silently through a load box or building a complete high-quality rig without a physical amplifier at all.
