Works as intended.
Works great and really helps you to get everything out of your H9
A Handcrafted H9 Auxiliary Switch
With the OX9 Aux Switch, you can control basically any function on the H9 - active/bypass, preset change, tap tempo, enable tuner, performance switch, parameter adjustments, bank up and bank down.
The OX9 has a laser cut bottom plate, so it securely attaches to your H9 without hiding any of its sexy contours!
Expression Pedal Compatible
The input jack on the OX9 allows you to add another button or an expression pedal. To get the most out of having two switches on the OX9, the right switch can be used as a HotSwitch or FlexSwitch for the parameter the expression pedal is set to adjust. It engages the heel-position functionality momentarily, which opens up more creative possibilities such as instantaneous octave bends or momentarily long delays.
