So, I have a 1st generation Scarlett 2i4 and when I use my guitar at the instrument input, I have this strange hum that increases or decreases as I do some things.
For example: When i put the guitar close to my body, the noise increases (00:02). The same thing occurs when i put my bare feet on the floor.
When i lift my feet, the noise decreases (00:08).
When i touch the strings, the hum gets quieter (00:13).
When i roll off the volume knob a little bit, the hum have more bass frequencies (00:17).
I recorded the noise to illustrate what happens. The times stamps above refers to the things that i said: https://soundcloud.com/onehundredyearsonnothing/hum
This happens either with humbuckers or single coils in diferent guitars.
Is this related to the audio interface? Or maybe ground loop issues?
Can this be guitar related?
A DI Box can help with the hum?
My computer is not grounded
Thanks in advance
