No more restraints to how you build your setup

The Duo offers far superior patching possibilities than any competitor. It's an entire world of new possibilities to musicians. With two independent audio channels, you can split, join, feedback, and rearrange your signal freely and discover an endless array of tones. Get rid of those rigid slots of old-fashioned multi-fx pedals and patch like in the real world and beyond.

signal freedom

The most versatile stompbox ever created

With three different pre-amps, choose the optimum input signal to any instrument while enjoying all the variety and flexibility of the digital world. Use it with your guitar/bass guitar and voice at the same time with full signal independency. Plug in a MIDI controller and add up virtual instruments to your gig - all in one single stompbox which features Audio, MIDI and USB inputs/outputs, offering maximum flexibility.


Shape it for every scenario

The MOD Duo was designed to be ultra-shapeable to your needs. Assign any parameters to the two multi-function knobs. Stack several controls on each knob and circle with a push. The two onboard footswitches allow you to switch entire presets, pedalboards, tap tempo, or simply bypass with your feet during a live performance. The Duo is a blank canvas for all your necessities both in the studio or on stage. Expand to maximum connectivity with MIDI Learn, by using it as a MIDI hub for multiple controllers at the same time or with the MOD Footswitch.

Frequently Asked Questions

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
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.
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.
