What could be improved in a version 2, that can't be done in the current hardware?
1) Two amp/cab possibilities. How about a parallel mode, where you hear two amps/cabs in parallel with the ability to pan them center or spread out in Stereo? How about a toggle mode so that the two amps/cabs could instead be toggled within the same rig? How about a doubling effect and controls for this in the amp block so that it sounds like two amps/cabs are being used when only one is?
2) How about one or two more effect slots on either side of the amp section with an extra effects block part of the parallel options we have in the current generation?
3) How about fully stereo signal path; mono by nature effects such as overdrives could be left in the center by default or panned left or right?
4) How about more effect loops similar to the Helix setup?
5) The ability to be an audio interface.
6) Bigger screen
7) perhaps six soft buttons along with 6 knobs above AND below the much bigger screen. This would reduce the need for as many feature specific buttons and knobs, since the bigger screen and extra buttons could be shared for many features.
