It’s the same dimensions as the HX FX and I have never had an issue with that.
And I have big feet and run it in stompbox mode or whatever they call it.
Well, almost the same size. Hx is 7.9” deep x 10.8” wide. Qc is listed as 7” deep x 11.4” wide. And a good portion of that depth is screen. And again, fewer switches on HX. If it’s comfy, great! Looks a little crowded to me. We’ll see.
