Hi All,
I have both my computer and my GT-2 clone connected to a mixer. I noticed a lot of noise especially on the high gain settings of the GT-2. Recently I realized the noise doesn't come from the GT-2/Guitar but from the computer. As soon as I connect the computer to the mixer there is a big increase in the noise level. I have an TFT screen, so the noise isn't coming from the screen, turning it off doesn't make a difference.
Did anybody else noticed such a thing? Or does someone has a good idea to get rid of the noise?
Thanks,
Joep
It's probably the fan...
shielding the guitar will probably help you TONS.
check out www.guitarnuts.com for some info....
It could be the switch mode power supply in the PC.
I suppose it would be possibe (though I have never heard of it being done) to run the PSU externally, some distance away, with mains type fileers on the power leads to the computer. (watch current ratings).
I think I have to agree that it's the fan. Try using a wah close to your CPU, and you'll pick up noise from the fan with no problem... and your pickups will, too. Shielding your guitar would probably help quite a bit.
Hi All,
Thanks for you answers, it made me thinking.
The noise isn't induced into the pickups or something, I tried walking away with the guitar and holding it very close to the computer. No difference. Actually, it I disconnect the computer from the mixer he noise was gone, the only thing I had to connect to the computer was ground to already have the noise. So that led me to the conclusion that Paul Perry was right.
I noticed I didn't use a grounded mains connection. So as an experiment I connected the ground from the mixed to a piece of clear metal from the central heating system (grounded), and the noise was completely GONE!!
I guess I really need an grounded mains connection.
Thanks again!

Cool. Sometimes grounding the power supply on something that doesn't have one fixes problems like yours. I have had some similar experiences.
OK, it took some effort but I made a grounded (wall) mains supply now. I had to add an extra wire because it wasn't there. Connected everything back again......
Noise is gone!
