The MOD Duo uses a revolutionary approach to multi-functional stompboxes. It provides a ton of sounds, effects and tools out of the box. But it doesn't stop there. With a MOD you can design devices for just about every musical and technical use-case – be it on stage, in the studio or at home.

The MOD Duo is a multi effects unit, it's a loop station, a synthesizer, an amp simulation and even a recording device.

The MOD has a very powerful, yet intuitive, graphical user interface, the Assembler.

With the Assembler you can create virtual pedalboards and it is one of the reasons why the MOD is so versatile: It allows to freely connect any combination of plugins – just like real audio hardware and pedals.

But that's just to get started. We set up a dedicated store where you can search for new plugins and download them directly from within the Assembler – with just 1 click. New plugins, free and commercial, are frequently published in the store by independent developers.

The MOD Duo utilizes an open standard for the plugins called LV2. It also features integrations for great audio technologies such as Max/MSP, Pure Data and Faust.

The Mod Duo is a pedal with software inside that you can reach via a webbrowser on the computer, you can connect via USB.

You can create effect pedal chains, for guitar, but aswel create chains for synths and other instruments to connect a MIDI keyboard etc...

The ModDuo has many many options under the hood, so many that I haven't figured out everything yet, it has endless possibilities.

I made a few pedalboards already in the browser and saved (and backed it up externally). You can use it in a live setting too, but I now use it in my recording studio to replace an amp and pedalboard.

The sound is very good, but I'm probably going to tweak some more later on when I have more time, but I want to record straight away now, can't wait :p... so I'll probably create other boards later.

I like the way it's open source and can be updated with lots of pedals in the future.
A nice extra is that there's a helpful community where you can exchange your own made pedalboards.

This is an incredible product ... Everyone should check out what they've done. The kind of power and freedom that's possible here is a bit mind-blowing to me. I really hope this kind of approach catches on.

Great work, MOD.
