I bought an H9 Max yesterday Friday and today i have tried using it but there are problems using it with
Bluetooth on my Ipad.
My H9 sometimes wont load a preset then when it does load the preset my guitar signal is dry.
That's a strange sounding problem. You might want to re-initialize the H9 to its system settings. You do this by turning it off and then turning it on again with the HotKnob switch pressed (the one in the upper left hand corner).
Are you seeing any error messages on the iPad saying a communication error occurred?
