Welcome to the OX Pedal Revolution

Unleash Your Pedal Without the Madness

To unlock the full potential of your digital pedal you need an aux switch.  It’s how everyone gets the most out of a $$$$ pedal.  But which aux do you get?  Will it even work with your pedal?  Or does it only work with Strymon or Merris or Boss?  Can you even tell?  

It’s time to stop this madness once and for all.  Finally there is an aux switch that works with almost any aux-able pedal.  And all that functionality comes in patent-pending, compact, custom form factors that take up less board real estate.

Meet the OXU series.  This isn’t just another aux switch; this is a revolution.

The Last Aux Switch You’ll Ever Need!

With the OXU’s patent-pending design, using a different pedal is as easy as flipping a switch

Industry Default Switching

Normal

This is the most common aux switch circuit that the vast majority of manufacturers use with their pedals. Some of the brands that use this type of switching are:

  • Eventide - H90, H9, dot9 Series, Factor Series, Rose

  • Line 6 - HX Stomp, HX One, HX Stomp XL, DL4 MkII, POD Express Guitar and Bass, POD Go

  • Digitech / DOD - Trio & Trio+, SDrum, Whammy DT & Rubberneck

  • Source Audio - Nemesis Delay, Ventris, Collider, etc..

  • Kemper - Profiler Player

  • Fractal - FM3

This is by no means a comprehensive list and we will be continually adding to it as we learn about new compatible pedals

Proprietary Switching

Strymon

This setting will work with Strymon pedals that use momentary switching like the BigSky, BigSky MX, TimeLine and Mobius. This will NOT work with the Volante or the NightSky as these use latching style switching.

Meris

This setting will work with Meris pedals that use momentary switching like the Hedra, Enzo, Mercury 7, Ottobit & Polymoon.

Boss

This setting will work with Boss pedals that use momentary aux switching. Some pedals that will work with this setting are pedals from the 200 & 500 series, GT-1000, RC-5, RC-10R, RC-202, AD-10, SY-300 & many others.

Three Sizes. Endless Possibilities…

All sizes work with almost every pedal that uses momentary aux switching

Two buttons, expandable to three (with our Tesla Tap) with a shorter length, making it perfect for Eventide H9 & Dot9 Series, Meris, Source Audio, and Boss 200 Series. Priced at $79.

Small But Mighty

Like our legendary OX9, the OXU series has an optional mounting plate that works with virtually any aux-able pedal. It’s also incredibly easy to mount - attach your OXU, attach your main pedal, break away the excess tabs, and you’re off to the races.

Our customers love the plate because it creates one seamless pedal and allows you to hang your OXU over those useless gaps on your board. No other aux switch gives you this level of versatility.

Explore The Endless Possibilities

Your OXU can be used seamlessly across different aux-able pedals with just a flip of the switch. Here’s a few of our favorite configurations.

If you want additional functionality for your OXU Standard or Mini, you can always attach a Tesla Tap to gain a third button. Or use the OXU Three and have three buttons in one enclosure.
