The Two Notes Opus is a compact pedalboard amp simulator and DynIR cabinet engine with Tube-Stage Modeling (TSM) preamp and power amp stages, MIDI control, and USB-C. It covers guitar, bass, and acoustic DI workflows in a metal chassis that sits on a board or next to an interface.

Amp Modeling and DynIR

Five onboard TSM preamps (Foundry, Peggy, Albion, Foxy, NiftyFifty) with room for more via firmware, plus power amp models (6L6, EL34, EL84, KT88) in push-pull Class AB or single-ended Class A. The DynIR engine loads dual-miked virtual cabinets with 8 mics per cab and room sims. Series-O DynIR cabinets are preloaded (32 cabs, including artist captures), and you can blend static IRs or use the acoustic DI pack with 40+ acoustic IRs.

Control and Effects

Edit from the dual encoders and OLED display, or use Torpedo Remote on iOS, Android, macOS, or Windows over USB or wireless. Onboard processing includes enhancer, noise gate, multi-mode EQ, and reverb. MIDI input (breakout cable included) handles preset and parameter control. Up to 99 presets ship with 40+ artist presets.
