It delivers sparkling clean tones with plenty of headroom and a switchable Boost for those rock-inspired riffs.
What sets the MF-484H apart is the Two notes Torpedo technology, offering emulations of 6 classic mic'd guitar cabinets. This means you can connect directly to a PA system, use a full-range on-stage cabinet, or integrate seamlessly with your DAW or recording console. The possibilities are endless.

But here's where it gets truly remarkable – the Torpedo output provides access to 6 virtual cabinets loaded with Celestion speakers, all mic'd with legendary microphones in ideal acoustic spaces. Whether you're on stage or in the studio, it's like having a van-load of cabinets and a world-class microphone selection at your fingertips. And yes, you can even edit the mic selection and placement via the convenient USB port on the back panel.

From a 1952 Filmosound to the latest official Ashdown
Engineering® cabinet series, Two notes have always pushed the envelope to capture the full diversity of guitar and bass cabinets.
Impulse responses are everywhere, everyone makes them but
they all share the same problem... They are static. If you don't like the tone when using regular IRs, or want to tweak something, you have no option but to remove it and then load another.

To get a comprehensive selection of tonal options you have to have gigabytes of .wav files stored locally. Every time you want to change
something you have to trawl through a massive library to find 'the one'.
This means you invariably end up using the same few IRs over
and over and your mixes start to sound stale and predictable. Two notes have always viewed this as standing in the way of creativity. To challenge this disruption to the workflow, we created a more dynamic version of the IR.

Meet DynIR, available for use with your Torpedo Hardware and Software.
You’d need a library of 160k perfectly phase-aligned studio-grade IR files to replicate each Two notes Virtual Cabinet. The magic with DynIR is that you don’t see any of it, you just move the mic around the cabinet in real time and hear the changes, as they happen.
Real time mic placement:
You can place the mics wherever you want around any Virtual
Cabinet. It’s not only much easier than comparing hundreds of standard IR files separately, it allows you to monitor how your tone changes while you move each microphone with your finger.
Front or Back:
Nothing give more depth and power to your tone than blending in a mic placed round the back of a cab. The true essence of flawless tone comes from taking the front mic’s precision and clarity and adding the unique thump and thickness only the back of the cabinet provides.
Dual Micing:
Each DynIR Virtual Cabinet is packed with 8 microphones carefully picked to bring out the uniqueness and character of the captured cabinet. From industry-standard Dynamic microphones, to prestigious Condensers all the way to antique Ribbons, there’s a world of tones to explore within each DynIR Virtural Cabinet. With Dual-Micing, you’ll achive perfect tones quickly and effortlessly.
