add4,  That was my business case exactly.  Excluding all the far out there things that would require a rebuild of hardware, The ability to load TF OS on a PF pedal is quite possibly already there from what I can tell.  and again, I would think it would increase in likelyhood of someone buying additional pedals as they get used to running them.  It's kind of a, "Well, now that you've invested in a new factor pedal, try these other versions of the same pedal for a fraction of the cost." Kind of like getting a free sample of what running more than one pedal would be like.  Or for my perspective, I might now want to drop another $350.00 on another pedal that would take up so much roon on my pedalboard.
