hello m8s.I have a nady XR-61 wireless system.Havent used it for a lot of time and when i got to use it again, i noticed that the tone of my guitar isnt the same as b4.It s like i lose some gain...like the tone of my guitar is dead.Especially when i use distortion.I ve changed the batteries in the transmiter but it s still the same.Could u plz help me out and tell me why this is happening and possible solutions?

Thnx alot
