Hi everyone. Since yesterday I have the new Garageband. I installed it to use it as an Amp/Effects for my new e-Guitar.

To plug the guitar into my MacBook I am using the esi ESU 22 audio interface. The problem is: if I turn on the monitor

in the Garageband to listen to me playing, I get a disturbing noise, even if I don't touch any string on my guitar! The noise gets worse or less depending on different amps, but still it's annoying. Is there anything I could do to reduce it or get rid of it?

 

Thanks a lot.

GarageBand (Mac) '11, Mac OS X (10.7)

    Not really sure what you mean by disturbing noise. But do you get this when you play on a track with no amps or effects?

    Sounds like a ground problem or a bad instrument cable or electrical interference. Try a different cable, turn off any lights or anything with a motor that is close to the guitar. If you have a real cheap instrument cable make sure it isn't crossing any electric cords. Also lower the gain on your interface.

     

    If you have single coil pickups on your guitar you will always have some hum so use a noise gate on the track.

    The fact that when you touch the strings and it quiets down would suggest that the problem may be a ground problem. This could be in the guitar, cable or electrical outlet the mac is plugged into. If the guitar and cable work fine with a guitar amp then we should look at the electrical outlet your mac is plugged into. Is the mac plugged into a electrical outlet or a powerstrip? Are there any other devices or appliances plugged into the same outlet?

    I just wonder did you solve the problem and if yes how ? I just bought Apogee Jam and Mic (both 96 K) and have exactly the same problem with both !! ( for a certain period of time they are extremely quiet and suddenly they become noise monsters after some period they may become silent again !!). As they are at 2 different interface (mic and Jam), and as tried their 2 original cables etc.. I do not believe the problem is originated from Apogee equipments...

     

    Pls explain how you solved it. Thanks in advance.
