Also, for next generation / Axe4 / FC:
A/D and D/A converters on the pedalboard(s) / FC units, and next gen FASlink connection- so we could have the option to directly plug in your guitar to the FC floor unit, as well as run one of the send/return loops from 1/4 jacks on the pedalboard... If you have additional outboard fx pedals you want to integrate, you could do it on pedalboard with FC unit.
(and improve the readability of FC strips... higher contrast between backlight and text + larger text)
