So I've been toying with the idea of getting a wireless unit...I'm not gigging currently, but I have for years in the past and may be again in the near future. My guitar tech had a Line 6 G10 Relay that he showed me and I was amazed by how well it worked and the tonal difference between the G10 and being plugged in regularly with a cable was really minimal. I was on the hunt for one (they're usually $180 new) and finally scored one last night from GC for $75 shipped. What wireless units if any do you guys use? I may want to upgrade to a higher end one at some point down the line and was curious to hear opinions. Thanks!
