Hello,
You cannot achieve this with a simple mono guitar + H90 + amp setup. The H90 routing does not allow that.
You could achieve this with a setup that has multiple amps as described here: https://cdn.eventideaudio.com/manuals/h90/1.9.7/content/setup/wet-dry.html
Your guitar would remain unprocessed in the “dry” amp, while the “wet” amp would have the Looper + Harmodulator effect.
If you had another pedal in your chain that split your signal before the H90, that would also work.
