The MOD Duo at a glance

Frequently Asked Questions

  • Are the audio plugins that run in the MOD Duo made only by MOD Devices?

    No. We have an online Plugin Store that is opened to 3rd party developers, similar to the app stores from smartphone. The MOD Duo supports an open standard called LV2 created by the very active Linux Audio Community and hundreds of LV2 plugins are freely available.

  • Do I need a computer or other similar device to play with the MOD Duo?

    No, you can take just MOD Duo to the stage and it works like any other regular multi-effects pedal. The computer/tablet/phone is used to install new effects; create pedalboards (plugin arrangements with control assignments); upgrade the internal software; and share your pedalboards on MOD Cloud.

  • Do I need to be connected to the internet to use the MOD Duo?

    No. You can create pedalboards using the plugins that are already installed on your MOD Duo. Internet connection is required only to install new plug-ins and to share or download other users’ pedalboards.

  • How is the MOD Duo updated?

    The MOD Duo checks if it is updated every time you connect to the graphical interface. If there is an update available, you will be notified. You can then perform the update with a single click. Our team of programmers and engineers work to develop new features and to improve existing ones. We launch new updates every month, which means that your MOD Duo constantly becomes more efficient and more stable.

  • Can I install plugins on the MOD Duo that are not available on the Plugin Store?

    Yes. Our devices fully support the LV2 standard and any working LV2 plugin will work in the MOD Duo. Installation is done using our open source SDK.

  • How many effects can I use simultaneously on the MOD Duo?

    The only limit to the number of pedals you can use simultaneously is the amount of processing they require. Certain pedals, such as Pitch Shifters and Tube Emulators, carry out numerous mathematical calculations and, therefore, require more processing. Others, such as delays and chorus, are mathematically simple and require little processing. Therefore, you may have problems if you try to use several Pitch Shifters on the same pedalboard. To help with this, the MOD Duo has a CPU usage indicator that alerts the user when the pedal board they have created is overloading the equipment.

  • How many plugin parameters can be adjusted via the controls on the MOD Duo?

    You have four actuators at your disposal: two footswitches and two knobs. The switches only allow you to control one plugin at a time but can be used to switch between pedalboards. The knobs, on the other hand, can be pushed like buttons so that you can address and control a virtually infinite amount of plugin parameters with each one, though it might not be very practical. Each musician can find the perfect balance between the numbers of actuators, the numbers of parameters to be controlled and the pedalboard banks that fit their needs.

  • How long is the MOD Duo's warranty period?

    Besides the 30-day money-back guarantee period, the MOD Duo has a one-year warranty, provided the problem is not caused by misuse. Our support team can also help you with any queries, regardless of when the MOD Duo was purchased.

  • How much latency is expected in the MOD Duo?

    The MOD Duo is designed to present the minimum possible latency. We use specific PCBs and circuits for audio processing, producing a latency of approximately 8 milliseconds. Our engineers are working to further reduce this latency.

  • Does the MOD Duo have a phantom power button for condenser microphones?

    No. The MOD Duo has a MIDI input and two mono-jack inputs for connecting guitars, basses and dynamic microphones, but a condenser microphone could be connected via a pre-amp with phantom power.

  • Does the MOD Duo run VST effects?

    No. The format used by the MOD Duo is LV2, which is similar to VST, but released under an open-source license, avoiding the license hassles related to VST and allowing multiple developers around the world to create effects for the MOD Duo.

  • Are the plugins free of charge?

    Currently all plug-ins available for the MOD Duo are free but the commercial section is already under development and will be opened soon. We currently have close to 200 plugins in our library and new ones are constantly being added.

  • What instruments can I use with the MOD Duo?

    The MOD Duo is designed to work with a big variety of instruments. People use the MOD Duo with anything varying from regular electric guitars to wind-instruments like the trumpet or a MIDI Drum Kit. A general rule of thumb: if it can be plugged in to a 1/4' jack,a DIN-MIDI or USB, it works with the MOD Duo.

  • How many instruments can I use simultaneously on the MOD Duo?

    The MOD Duo has two completely independent analog inputs plus it supports both DIN-MIDI and USB-MIDI controllers. You can use a USB-Hub to connect multiple USB-MIDI controllers. The Plugin Store offers an comprehensive colletcion of virtual instruments and synths, including a great suite of MIDI processing tools.

  • Does the MOD Duo support MIDI?

    Yes, the MOD Duo has great MIDI-connectivity. There is support for old-school MIDI over DIN-cables, as well as USB-MIDI over USB-cables. It is even possible to add a USB hub to the MOD Duo to expand the amount of USB connections that you can make.

... And this is what musicians who already use the MOD Duo say about it ...

  • "Initially, you get excited with the number of effects. For me, the basic ones are important: the clean, the drive, the crunch, the distortion. They are all there. It's endless fun!"

    Kleber K. Shima, guitar player, music teacher and producer São Paulo, Brazil
  • "With the MOD Duo, I don't care if the gig has a shi*** amp. My sound will always be there."

    Niper Boaventura, leader of the band Pull Down São Paulo, Brazil
  • "Here we have all the effects together without having to buy each one of them. I was looking for that for a long time."

    Marcelo Coelho, sax player, soloist, music teacher, composer and producer São Paulo, Brazil
  • "I spend a lot of my time recording with, trying out and writing about pedals and processors - my music career depends on them, and as such, I'm very demanding of them. The MOD Duo is at the heart of my live and studio set-up, and has helped simplify my set-up while simultaneously increasing the options available to me at any one time. I love it."

    Steve Lawson, solo artist, Bass Guitar Magazine columnist, music lecturer Birmingham, UK
  • "I've tinkered enough with embedded devices and audio to realize that the MOD Duo is the end of the line, it's the best, it is practically unbeatable in its category. And other companies have tried but none of them managed to deliver a product like the MOD Duo."

    Jeremy Jongepier, guitar player and software developer Beverwijk, the Netherlands
  • "It seemed too good to be true at first: the tone customization and being able to save presets for fluidity during shows, the wide variety of pedals, lack of bugs and glitches and user-friendly UI. But now I call it the pedal from heaven. It's perfect for college students wanting a pedalboard with little money. It's a big step but it's the only pedal you really have to own. Amazing!"

    Richard Jacob McCauley Wenzel, electric guitar player Huntersville, USA
  • "An innovative tool that could grow into something special."

    Niklas Ollikainen, Electric guitar player Malmö, Sweden
  • "It can really do anything: audio in/out, midi in/out, etc, plus it has its own plugin store, community and is its own independent platform. If I didn't have the MOD Duo, I would have to go back to boring FX pedals from big companies, while now I have the most amazing FX board in the world!"

    Vincent Rateau, Electric guitar player for Superdirt Freiburg, Germany
  • "A really great-sounding musician nerd toy."

    Frank Lehmann, Electric guitar player Auckland, New Zealand
  • "I was worried at first if MOD could follow through and deliver on its promise of an all-in-one device that could replace several others. But it has! You've gotta try this! I replaced several pedals and sold them (used on e-bay) and made enough (and more) to pay for the MOD Duo."

    Dave Parker, Electric guitar player Kansas City, USA
  • "I have been using the MOD Duo since September 2016 for my electro-accordion project, and have been enjoying the compact nature of everything being in one pedal for my live shows, the variety of effects there are for both my vocals and for my accordion and how user-friendly the pedalboards are to build. In addition, the staff at MOD Devices are always very helpful and super attentive to when I have any questions regarding their product."

    Miss Natasha Enquist, Electro-Accordion Chanteuse, MNE Records Berlin, Germany
  • "My live setup is now several kilograms lighter."

    Jóhannes Gunnar Þorsteinsson of void Ziz() Iceland
