It was fine on my other computers but on my laptop my guitar hums like mad. I don't know what it is, any ideas?
it may have something to do with ur laptop screen and the pickups....and how close they are to each other.
My toneport just started humming too today.. On the same computer, same cables,... Don't know what to do either..
Is it when you play the guitar it makes like a really terrible sound, or without even playing it hums?
Have you tried plugging the power supplies for your Toneport and your laptop into the same plugboard?
If it is humming and you are close the a computer or other device that emits electromagnetic waves like that, you should try using the Hum Reducer in the Gearbox.
It won't be the screen because it's not a CRT monitor if it's on a laptop.
