Two Notes' Magnum Opus The Two Notes Opus is an all-in-one rig replacement in the size of a standard stompbox, providing you with utterly authentic amplifier emulations and the immensely powerful DynIR engine. Inspired by Two Notes C.A.B. creations, the Opus adds fully featured preamp and power amp modeling sections, allowing you to craft your dream amplifier from the ground up. Next, the DynIR Engine covers the rest of your signal chain with a vast library of beautifully emulated guitar cabinets pulled from throughout 6-string history, all with the ability to choose your own mics and rooms for pristinely produced tone. You also get a myriad of must-have utility effects (reverb, EQ, noise gate, etc.), 99 preset slots, Dual Static IR loader, and MIDI functionality for superior control.
