Hey guys...sorry if this has been done before but I found a audiotechnica p80 wireless guitar system at a local music shop..now it might be a typo on ther site I think its a p90 but anyways..
Is this a good wireless system?
Pros and cons?

Would it fit in with my rig?
I play a gibson sg faded into a peavey 5150 with a marshall 4x12 no other effects but a chorus and a tuner.
Would using a wireless system drastically effect my tone?

Thanx for the help!
