I've gigged my X2 Digital system (new X-Wire) three times now with 100% favorable results.
And since the receiver is pedal-sized, I just set it down on my pedalboard somewhere where it can fit and then put it back in it's box when I'm done.
I'd thought about hard-mounting it, but that's just an accident waiting to happen!

Then I just run one cable to my amp, and I'm good, with pedalboard and all my FX running smoothly!
