About This Item
Description
The OX9 gives an Eventide H9 the two extra footswitches it was always missing. It attaches to the pedal itself, so preset changes, bank changes, tap tempo and the tuner move from a menu to your foot without taking up extra pedalboard space.
The OX9 is a handcrafted Barn3 auxiliary switch designed around the original Eventide H9 chassis. It carries no audio and adds no effects of its own: it simply drives functions the H9 already has. It is not compatible with the H9 Harmonizer Gen 2, whose mounting holes, cable and inputs are different.
Why H9 owners add the OX9
- Two programmable footswitches control basically any function on the H9: active/bypass, preset change, tap tempo, tuner, performance switch, parameter adjustments, bank up and bank down.
- A laser-cut bottom plate attaches to the H9 without covering its contours, so there is no extra enclosure and no lost board space.
- A custom molded low-profile plug keeps every jack on the back of the H9 accessible.
- The OX9 has its own input jack for another switch or an expression pedal, so you keep expression control.
- Every unit is assembled, tested and packaged by Barn3 in Klecknersville, PA.
Controls & Connections
- Two footswitches: each is assigned in the H9 aux switch settings.
- Input jack: accepts another button or an expression pedal.
- Low-profile plug: connects the OX9 to the H9.
Using an expression pedal with the OX9
- Requires H9 software V4.8 or later.
- In aux switch mode, both footswitches control H9 functions.
- With an expression pedal plugged into the OX9, the left footswitch stays assignable to an H9 function, and the right footswitch can act as a HotSwitch for the parameter the pedal controls, jumping momentarily to the heel-position setting for instant octave bends or momentary long delays.
Compatibility
- Designed for the original Eventide H9.
- Not compatible with the H9 Harmonizer Gen 2.

FAQ
What does the OX9 actually do? It adds two programmable footswitches to an original Eventide H9. Active/bypass, preset change, tap tempo, tuner, performance switch, parameter adjustments, bank up and bank down can be placed on the switches, so you do not have to bend down to the pedal.
Does it work with the H9 Harmonizer Gen 2? No. The OX9 is designed around the original H9 chassis; the Gen 2 has different mounting holes, cable and inputs.
Do I lose my expression pedal input if I use an OX9? No. The OX9 has its own input jack for an expression pedal or another switch; expression through the OX9 requires H9 software V4.8 or later. With a pedal plugged in, the left footswitch stays assignable to an H9 function and the right footswitch acts as a HotSwitch for the parameter the pedal controls.
How is it attached? A laser-cut bottom plate attaches it to the H9 without covering its contours, and a custom molded low-profile plug connects it, so every jack on the back of the H9 stays accessible.
Does the OX9 process audio? No. No audio passes through it at any point, so it cannot color your tone. It is purely a control accessory.
Where is it made? Every OX9 is assembled, tested and packaged by Barn3 in Klecknersville, PA.
