Hello friends, I communicate from Argentina. I have a serious problem with my hd 500, in all the sounds of "solos" feeling a saturation noise, noise "pen" or "pua" as we say here in Argentina, it happens with all the sounds, and not that else to do .. try with compressors, limiters .. but nothing, I can leave audio samples if necessary.

data:

Ibanez rg 350 mz
Strings 10/46 Ernie Ball
Dimarzio John Petrucci Mics
Pua Dunlop John Petrucci.

Thanks and sorry for my bad English, lol.
