Hi Peter,

Either of your proposed setups should be fine.

In your first setup, you need to use Dual Mode, which will allow you to put either of the H90’s presets before or after the Tonex.

The second setup would be used with Insert Mode, and this would allow you to use additional pedals in the H90’s insert paths using I/O 3-4. You could try using the Walrus Canvas Stereo as a stereo insert instead of after the outputs of the Tonex, or you could try using the Tonex as an insert as well.

There are many options to experiment with and find out what works best for you setup. My best suggestion is to try different setups and see what you like.
