Has anyone tried out this new Wireless unit? I am looking to get a wireless. This would be a cheap and simple way to get a wireless setup. Of course, on a product like this one they don't list the specs at all, and so i am wondering if anyone has tried it on a 5 string or just knows the frequency response. I want to know how the lows are on this unit? If this one if bad, what can you guys recommend for a 5 string?
