I replied to you via GearHeads. But here it is again for the benefit of others....
Hi! Hope this helps:
1) How do you guys use your tuner and wahs with the unit? - Don't use a wah but you could use a rack wah or go: Guitar > Wah > GCX input. I use a rack tuner and do a send to the tuner without a return so it automatically muted via GCX technology.
2) do you have any favorites in terms of enclosure units? - I use a RoadReady effects rack. It is less shallow than the standard rack which cuts down on weight. I put my pedals on a shelf that I completely vecro'd.
3) There are two switchers a ground control unit and a ground link unit. Do you use them together? - Yes they can be used together or independently. There is also a ground control Pro. Or you could use other MIDI switchers. It all depends on how hi-tech you would like to be and how much tap dancing you'd do. I like the GroundLink and don't mind tapping.
Also, if you do a shelf I recommend using thumbscrews for the rack so you don't need a screw driver to remove the shelf.
