Overview

The Barn3 OX-9 is a two-switch auxiliary controller built specifically for the Eventide H9 multi-effects pedal, addressing one of the H9's most discussed live performance constraints: its single onboard footswitch. By connecting to the H9's auxiliary input, the OX-9 adds two independently assignable touch-sensitive switches that can be mapped to tap tempo, preset scrolling, bypass, looper controls, and other performance functions within the H9's parameter ecosystem. The touch-sensitive mechanism registers intent at contact — before full physical compression — which tightens the effective response window compared to standard momentary switches. For tap tempo specifically, this produces more accurate BPM locking with less deliberate force.

The OX-9 is the right solution for the performing musician or studio guitarist who runs the H9 as a centerpiece effect and needs more than one foot to drive it. It draws power directly from the H9's auxiliary input, adding zero load to your pedalboard power distribution. The compact form factor — 6 x 6 x 4 inches — fits between pedals without claiming a full slot. The included protective case keeps it road-ready for transport. The IP00 rating is the practical limitation: this unit has no environmental sealing of any kind, making it unsuitable for outdoor or wet-stage use without independent protection. In controlled environments — studio sessions, club stages, rehearsal rooms — it delivers clean, low-latency control expansion for a pedal that otherwise demands constant menu interaction to access its full capability.

Pros & Cons

👍 Pros

  • Two independently assignable switches expand H9 control without requiring a full MIDI controller on the board
  • Touch-sensitive switches register contact before full physical depression, producing tighter tap tempo and faster preset response than standard momentary switches
  • Bus-powered via the H9's auxiliary input — no dedicated power supply required on a packed pedalboard
  • Compact enclosure occupies minimal pedalboard real estate compared to adding a full auxiliary footcontroller
  • Includes a protective carry case for transport without damage to the switches or housing

👎 Cons

  • IP00 ingress protection means zero splash or dust resistance — unsuitable for outdoor stages, festival conditions, or wet floors without additional protection
  • Compatible exclusively with the Eventide H9; not a universal auxiliary switch solution for other pedal brands or most other Eventide models
  • Two switches may be insufficient for performers needing simultaneous bypass, tap tempo, and preset scrolling — a three-switch solution would be required
  • No LED indicators on the switches to visually confirm which function is active or assigned at a glance in low-light stage conditions

Frequently Asked Questions

The switches are assignable to any function the H9 exposes via its auxiliary input — common assignments include tap tempo, preset increment/decrement, bypass toggle, and performance parameter controls like looper functions. Assignments are configured through the H9 Control app or directly on the pedal.
No. The OX-9 is bus-powered through the H9's auxiliary input. It draws no additional current from your pedalboard power supply, which is a meaningful advantage on boards where every power tap is occupied.
Via the H9's dedicated auxiliary input. The connection uses a standard auxiliary connector — no adapters or converters required. Plug in and assign your switch functions through the H9 interface.
The OX-9 is designed and marketed specifically for the Eventide H9. Compatibility with other Eventide pedals depends on whether those pedals support a standard auxiliary switch input — consult Eventide's documentation for your specific pedal before assuming compatibility.
Touch-sensitive switches register contact before the physical switch depression completes, which reduces effective triggering latency compared to standard momentary footswitches. For tap tempo applications on the H9, this produces tighter tempo locking with less deliberate stomping force required.
