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!

  • 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 super-versatile 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 Folks…

    Holy cow! This product absolutely answers all my apartment home recording prayers and them some!! GASSING like a mofo! LMAO!

  2. Nicolas says:

    Hi. Where can I upload more presets for the cab M +? I see that the Opus device has 60 more presets than the cab…. I would be interested to copy some of the opus presets features (what is not preamp dependant). Like the Jimi in Manifold one. Is there a forum for cab M users ?

  3. Nash Smith says:

    Hi there! I’m really intrigued by this product! This might be a silly question. Can I use this with an attenuator? For instance, place it after my head and attenuator so I can use the cab sims via recordings or between the attenuator and cab so I can use my attenuated amp live and use your IR’s in the mains?

    • ross says:

      Hi Tom, Thanks for getting in touch. OPUS cannot be used as an audio interface as the USB connection is reserved for Remote connectivity and data transfer only.

    • ross says:

      Thanks for getting in touch – Ross from Two notes here. Controllers compatible with conventional MIDI norms and protocols are all compatible with OPUS in accordance with sending PC and CC messages. Let us know if there is anything else we can help you with today!

  4. Alex says:

    Stupid question, but is there anyway the Opus can send a true stereo signal? I’m searching for a device EXACTLY like this but with stereo capability. I was so excited to see this product released after hearing rumors but was a little let down when I didn’t see stereo mentioned in the marketing materials.

    • ross says:

      Hi Alex, Thanks for getting in touch. This is a Mono device so it cannot output a Stereo Signal. May I ask why a Stereo signal is paramount in the context of your rig? Maybe I can devise a workaround for you!

  5. Teuvo says:

    Great product but is there any chance to have also a delay in a future upgrade? I still remember the upgrade from CAB M to CAB M +, there were more features.

    • ross says:

      Thanks for getting back to us and we’re so pleased to hear you like the product. Sadly integrating a delay wont be possible, but you can rear-load OPUS with a delay pedal and achieve some fantastic results!

  6. JB Borja says:

    So far really like the Opus. Still have the M+, love the preamp in it , any plan in the future to have the preamp in the Opus?
    Thank you

    • ross says:

      Thanks for getting in touch. You should find Foundry very similar to the preamp in the C.A.B. M+ – very few tweaks were made on this in terms of the sonic output actually!

  7. Justin smith says:

    Do I need a load box if I run my amp Friedman Runt 20 xlr output (mic-no-mo) to the input of the opus? Then, with no speaker connected, I can use headphones and or go to a DAW, or would that blow my amp up? Dave Friedman says that you don’t need a load box with the xlr cable ONLY on the runt 20 series, the runt 50 series wouldn’t work, JJ Jr. Is a part of the Runt 20 series.

    • ross says:

      Hi Justin, Thanks for getting in touch. Ross from Two notes here. You can certainly action this without a load box as the amp in question features an internal load for this output. However, this is a cabinet emulated output and you may not get the best results running a DynIR cabinet emulation on top of this. For optimal use, we would suggest combining an OPUS with a Captor and running the OPUS between your Amp’s Speaker Output and the Captor. Please let me know if there is anything else I can clarify for you today.

  8. Rob says:

    I love the sounds I’m getting from the OPUS, but I still need to use an external preamp for now. I use a Dual Rectifier for most of my music. I hope a Dual Rectifier-like preamp will be offered some day in the future. Please don’t offer a Soldano-like preamp in its place, as they are not the same.

    • ross says:

      Hi Rob, I hope all is well and thank you for getting in touch. We cant reveal too much at this stage but there are most certainly some high-gain pres in the pipeline! Let us know if there is anything else we can help you with.

      • Robert Shelby says:

        Thank you Two notes team, for the Dual Rectifier. You all nailed the nuances I look for in this preamp model, that many many manufacturers fail at delivering. Bravo!


    Can I switch presets on the Opus by sending midi PC messages from my DAW (via usb) or do I need to buy another usb to midi interface?

    • ross says:

      Hi Raymond, Thanks for getting in touch – Ross from Two notes here. OPUS does not feature MIDI over USB and as such you will need an interface that can transmit PC MIDI messages. Please let us know if there is anything else we can help you with.

    I bought the Opus as I have been extremely satisfied with the Torpedo Captor X – incredible device. However Opus is something completely different. I tested it for hours trying to like the device … It is built like a tank, all the connections are there, options etc. Unfortunately the sound is not. I don’t like comparison but with all the pedals I have on the pedal board – this little device is similar to Zoom devices when flooded the market end of 90s. I tried all possible combinations with my amps – Fender DRRI and AER Alpha, electric and acoustic guitars – I could not get the same sound out of it no matter what I tried and I tried … it simply us not there yet. In terms of integrating this into my rig I do not see this pedal as useful in live situations. All the drive sounds are terrible noise generators, the acoustic guitar emulations are not even worth mentioning. After discovering this is not going to end on the pedal boards I tried connecting directly to my Audient and see if I could use it for recording purposes. I was again disappointed – yes it is better but nothing that I cannot already achieve with Torpedo Captor X – I will not discuss the quality of the IR. The device itself is well engineered but the quality in comparison to my rig is under 25%. I mean if you do not have a pro quality tube amp go for it but if you do then better invest into Torpedo Captor X – that is one of best devices you will own. Opus – my 5 cent … 2 stars max.

      Hi Ash, Thanks for getting in touch and we’re sorry to hear you think like this? We are a little concerned as your comments don’t reflect the majority of our customers out there? In terms of your pedalboard rig, which preamp were you using? Did you have the line out routing set to full routing from the preferences? We would love to discuss this with you further via our support desk if you are open to this as we think there may be an issue with configuration or the device itself here – if you could create a ticket at we will assist in any way we can!
