Urban amp

I am curious, if you bought a Keith Urban guitar set that included an amp, please read and respond. This same amp comes with the solid body electric and the acoustical electric. I bought the solid body electric. You can fine my review in the electronic section as well as some other info. So, my amp is very noisy, lots of static and what sounds like electrical noise. The manufacturer replaced it once, but there was no real improvement. What I would like to know is if anyone else has a similar problem and if so how did you deal with it? I suspect that it is just a problem related to the overall quality of the amp, but it would be helpful to know if others have had this problem. 

Thanks.
