The H9 has a Pre/Post routing configuration that allows you to place certain presets on the “Pre” path and others on the “Post” path. You can find this setting in H9 Control by going to Pedal Settings > Routing. However, Pre/Post is limited to 2 mono paths because the H9 only has 2 inputs/outputs, so you would not be able to use stereo effects in the FX loop.
