Sorry about the late reply I didn't get a notification... just seen it now.
The bass pack will be migrated but this means we will need to make new profiles from the ground up so it will take some time. We have migrated the AV4B (Ampeg V4) and yesterday just added a new T&B Mk3 B (Selmer Treble & Bass).
Any progress on this? I'd like to purchase them when they are ready.
