The V-UNO X from OPFXS is a next-generation multi-effect pedal designed for guitarists and bassists who want maximum flexibility, powerful sound processing, and deep control—all in a compact unit. With the ability to load effects from the dedicated V-UNO X Editor app, assign parameters to its onboard controls, and integrate seamlessly with MIDI, the V-UNO X is more than just a pedal—it’s a customizable effects workstation.

Total Effect Freedom

The V-UNO X lets you download and run effects across a wide range of categories, including:

  • Gain – boosts, overdrives, distortions
  • Modulation – chorus, flanger, tremolo, phaser, and more
  • Synthesis – octaver, guitar synth, sampler, ring modulator
  • Filtering – parametric EQ, multi-band EQ
  • Dynamics – compression, noise gate
  • Impulse Response (IR) – load your own IRs for amp and cab simulation
  • Other – hybrid and combo effects that push sound design further

Two Powerful Modes

  • Preset Mode – Load one effect (or a combo) and save up to 3 presets for instant recall. Footswitches and buttons can be assigned to toggle bypass, change presets, or control effect parameters.
  • Bank Mode – Store up to 3 separate effects or combos in the pedal at once and switch between them on the fly.

Hands-On Control

  • Fully assignable controls via the V-UNO Editor: 5 knobs, 3 buttons, onboard footswitch plus support for remote switches and expression pedals.
  • Dual-action footswitch with independent short-press and long-press functions, fully customizable in Preset Mode.
  • Smart assignable LEDs that can be linked to parameters—like showing LFO speed and depth on modulation effects—for real-time visual feedback.

Connectivity for Every Rig

  • Stereo input (TRS) and dual mono outputs (A/B)
  • Remote/Expression input for external footswitch or expression pedal control
  • Full MIDI integration (Input + Thru), supporting CC and Program Change
  • USB-C for power, firmware updates, effect management, and real-time editing
  • Standard 9V DC power input (center negative, 200mA recommended)

Built for the Modern Player

  • True relay-based bypass for transparent tone when disengaged
  • Onboard memory to save and recall presets without a computer
  • Firmware and editor updates keep the pedal future-proof
  • Protection features against overvoltage, polarity inversion, and overcurrent

Deep Integration with the V-UNO X Editor

The free V-UNO X Editor app (Mac/Windows) lets you:

  • Browse, load, and upload effects into the pedal
  • Assign pedal knobs, buttons, LEDs, and external controls to any parameter
  • Load custom IRs for cabinet simulation
  • Save and manage unlimited configurations locally
  • Upgrade firmware and editor directly from the software

MIDI Control (CC & PC)

  • Map up to 16 effect parameters to MIDI Control Change messages
  • Recall presets and banks via MIDI Program Change
  • Selectable MIDI channel or Omni listening mode

The OPFXS V-UNO X

Compact, flexible, and endlessly customizable—the V-UNO X gives you the freedom to design your sound without limits, whether you need a single go-to stompbox, a mini multi-FX unit, or a MIDI-ready brain for your pedalboard.
