If the Hard Fuzz is not a Fuzz Face model, or at least doesn't sound like a Fuzz Face, and the FF is a widely-used sound/type of fuzz, shouldn't we ask Cliff to add an authentic Fuzz Face model to the Axe? Called "Face Fuzz" perhaps? I can't judge it's verisimilitude, fuzz is not my forte, just drawing the logical conclusion out of the discussion.
As for the Fuzz Factory, seems like it's a well-liked but finicky effect that some feel would be great to have, others feel is too specialized to bother including. If the Fuzz Factory is in essence a highly tweakable Fuzz Face, perhaps one solution is to add a Face Fuzz AND add lots of advanced-page tweakable parameters to the Drive block, covering most or all of the ground of the Fuzz Factory (and maybe more) but also allowing for lots of other sounds by applying those same parameters to other drives. That might satisfy the Fuzz Factory fans while also benefiting everyone else who uses drives and is looking for some unusual sounds. Again, just drawing the logical conclusion out of the discussion.
