That second unit does not look like an H9 Max. Contact firstname.lastname@example.org for them to verify. Under normal circumstances, Eventide allows a Max owner to download the algorithms to other Standard/Core H9’s on the account. But this DOES NOT turn those Standard/Core units into actual H9 Max pedals; if those pedals are ever deregistered they go back to being what they were.
Did this person purchase the MaxOut or not? Contact Eventide support for clear answers.
