I think there's an argument for questioning the need for wireless at all if the gigs are all pub based. The only reason I bought one was because the 80's show requires movement on sometimes quite large stages. That said, I do also use it for pub/club gigs because it's already on my board. I'm not sure the GLXD even qualifies as tour grade. You can spend an awful lot more on more powerful units.
Yes, it's expensive, but in my opinion, it's worth it. I've probably saved its value in AA batteries had I still been using the Line 6 🤣
