I have an FCB1010 with the Uno chip that I will sell you if you want. It works fine. As I recall, main disadvantage compared to other controllers is you can't autoload presets so you see the preset name on the controller. I think you just see the number. Also, IMHO these are not very easy to program (but I am 53 and behind the tech curve)
I believe it does tuner, but I am not sure about tap tempo. Patrick Voes made a great site on how to use this with the AXE here
