Carlos,
I don't hear ANY hiss, buzz, pops or clicks on your music. How do you get such a clean signal capture on that guitar? Give us an idea of your gear you use for capturing the guitar, please?

Cabling used?
I don't think I ever heard an internet recording that didn't have some type of hiss/buzz going on with a guitar recording. Yours is flawless.
What gear do you have in your rack there, LOL ?
Thanks,
Trax
