I have used on , and still have it, even though it is 10 years old
Mine lost a little signal, but never enough to throw me of
I am guessing that a new one would have a better signal strength
they are fun but end up being just another thing you have to make sure you bring all the parts and it keeps working
overall I am glad I have it even thought I don't gig anymore
on a side note, I was the one who had the most stage presence in our band , so the singer did not like me leaving and letting the stage get dead
Did this help,or am I just rambling
