OK... I was probably mistaken but I was under the impression that I 'acquired' the firmware update while purchasing the new HD Model Packs, http://line6.com/store/downloads/hdmodelpacks?cart_action=add_item&store_items_id=355&method=purchase
but you're saying that the firmware update was a separate 'free' upgrade.... well in that case I would say that they way Line 6 have marketed this whole release of the new models implied that to get the new functionality (Global EQ) I would also need to purchase the new HD models.... and then it doesn't work with L6 Link anyway which was never mentioned ...
I may have acquired the new models anyway but it wasn't clear, at least to me, that that the firmware upgrade was free.
