Ladies and gentlemen, may I be so bold as to give you an experiment to try.
Go to the local music store. Grab an amp, a guitar, a decent cable, and then the X2
digital wireless system. Preferably the XDS-PLUS because its dual diversity. Guitarists, find an EBMM John Petrucci signature 7, and a Mesa Mark V and 412 traditional cab loaded with C90's. Bassists, try a Tobias Growler 5 or Killer B5 and an Eden WT550B into two
D212XLT's. Hell yeah, that's a biased recommendation. Too bad, suckas.
Play your setup with a cable, and then swap to the X2.
I did this with a 5 string bass, to hear the low end. I heard nothing different. At all. Went home, tried the same thing with all my gear AND included my old Nady regular wireless. I dialed up my bass knob on the amp to compensate for the tone sucking. With the X2, I ran my amp FLAT. Everything at 12 o'clock. Clean. This proved that standard radio frequency wireless systems are GARBAGE compared to my X2 digital system.
In my band's practice room, I've been getting tons of 60-cycle if I lift my fingers off the strings. It was especially worse when I pointed the pickups at the halogen track lights. Swapped to the wireless, all noise gone. My X2 system is a glorious revelation of freedom AND great audio quality. And it has never glitched on me during a gig. Had it for well over 2-1/2 years how, dozens of shows and practices, never one problem.
Digital wireless is my friend.
And it can be your friend too.
