SFM is excited to share that Two notes Audio Engineering, the world leading innovator and manufacturer of load boxes, attenuators, and digital cabinet emulators, has just announced the OPUS. Building upon their C.A.B. lineage—and critically acclaimed digital cabinet simulation legacy—OPUS adds Pre- & Power-amp Tube-Stage Modeling™ (TSM™), MIDI integration and a future-proofed USB-C specification, empowering players of all-walks with apex-level tone in a go anywhere footprint.

For deft ease-of-use, Torpedo Remote (iOS/Android/MacOS/Windows) serves as the nexus of your tone shaping experience; simply hookup to your Phone, Tablet or Desktop and experience liberated 1:1 integration with every editable parameter in the OPUS architecture. Tonally, everything you demand from a state-of-the-art digital Amp Sim is here; whether it’s a thundering high-gain onslaught, a sublime clean primed to serve as the foundation of a pedalboard rig or a mojo-fuelled brit-inspired roar, each and every base is covered. OPUS, it’s more than a masterpiece: it’s a back-line in your gig bag and a macrocosm of next-level tonal excellence.

TSM™ Preamp Emulation

It’s a stone hard fact: the rudiments of stand-out tone start with an expertly tuned Preamp. TSM™ emulation furnishes players with a suite of pro-grade Preamps, brimming with unique character and inspired by icons in the guitar- and bass-amp annals.

  • Foundry – Whether it’s a pristine high-headroom clean or a primo foundation for your pedal collection, Foundry delivers. In short, it’s the epitome of a classic Cali clean, brimming with warm saturation and engineered to capture every subtle nuance of your delivery.
  • Peggy – Bass players seeking the pinnacle in low-end theory, look no further than Peggy. Pushing complex harmonic overtones, a warm midrange, and oodles of rafter ratlin’ thump, Peggy delivers the perfect blend of classic ’60s bass sonics with expertly tuned tweak-ability to sit your tone in any pocket!
  • Albion – For those times when only a legendary Brit-inspired roar will suffice, there’s Albion. Complete with a rich vocal mid-range, lashings of punch, boatloads of power and gain-for-days, Albion is your secret weapon when diving head-first into Classic- and Hard-Rock territory.
  • Foxy – Seeking chime, articulation, and buttery-smooth presence? Foxy’s a one-stop-shop! With airy highs, impeccable breakup, and sublime mid-range bite when pushing the gain, Foxy is primed to take on everything from sultry Jazz to rauch-fuelled Rock n’ Roll.
  • NiftyFifty – Want gain? NiftyFifty’s got it on tap! It’s aggression incarnate. It’s punchy. It’s superversatile covering everything from a warm full-throttle onslaught to a searing lead tone that cuts through any mix. Whether it’s the darker side of metal or a tone that wouldn’t be amiss in 80’s inspired virtuosity, NiftyFifty is deserving of any contemporary player’s sonic arsenal.

And That’s Not All…

For the ultimate future-proofed tone-chasing experience, Two notes HQ have confirmed there are even more TSM™ Preamps on the way, available as free Firmware Updates!
