Hey man thanks for asking. THe Xvive works fine for when I practice at home but anytime I am playing where there is WIFI it is pretty much useless. There have been shows where I can use it with just some background high-pitched hum. The last couple of shows it has been pretty much worthless as I not only have the high-pitched hum but it interferes with the wireless for my bass which is completely unacceptable.
The primary reason I am wireless is because I am prone to tripping over or getting tangled up in cables - not because I am playing massive stages in arenas. I would strongly recommend against the Xvive. Save your money for a system that is not 2.4GHz.
I don't wanna de-rail the thread more than we've already done, but here I go anyways...
@DELACIUS I've been using the XVive U2 system myself for over a year now, and it's been absolutely brilliant thus far. Have taken it on international tour, played outdoor stages, big concert halls, little pubs, and most sized venues in between. Never once has there been an issue with noise/interrupted signals. Battery life has been quite strong, too.
I'll be honest, I was hugely skeptical, since the name of the company looks alarmingly like a sex toy, and I'd never heard of them. But so far no problems!
Actually, that's not true. When I have this one student come over for bass lessons, and *only* when he is over for bass lessons, the signal has cut in/out on me before. I can't recreate the issue at home when he isn't here, nor has it happened at any other place under any other circumstances... maybe it's his gravitational field? LOL.
And, to make sure that I've at least attempted to *re*-rail the thread, here's my compact pedalboard (complete with XVive receiver!) from a gig Tuesday night. In this case, I'm meaning "compact" in the sense that all the pedals are smooshed in right close in on each other, with there being (almost) no wasted space on the board.
