I recently had a death of our guitar player (the other guitar is in my band) his father gave me his pedal board which has an h9 max and two cores on it how do I get them unregistered to him and register them to me? This has all been incredibly heartbreaking for me I hop this isn’t a huge hassle. I don’t know who to contact or if I just register them under my name? Thank you in advance for any info on this.
