I have used a cheap Nady wireless system from my acoustic guitar to the amp. It works pretty good , Havent had any interference. I think I paid around 50 bucks for it a few years ago.Be sure to use rechargeable batteries. they seem to eat batteries for lunch. I use Lithium rechargeables and they last a lot longer. So far I have never had a battery run out during playing and I have played about 3 hours on a single charge.Heres a similar one ;www.musiciansfriend.com/pro-audio/nady-dkw-3-gt-guitar-wireless-system?rNtt=nady%20wireless%20guitar&index=2
