I have a general question for any TWA owners. Is it normal to hear the TWA by just powering it on? With it unplugged, or unattached even, I hear a slight electrical hum just powering on the device and was curious if this just normal operation.
In a very quiet environment, you may hear a slight background hum if you put TWA close to your ear. Do you hear it through your guitar when attached?
It's a definite pitch coming from the TWA device itself. It's around a B flat several octaves above middle C. With the TWA attached, I can hear it in the sound hole as well, but only if i put my ear directly in front of the sound hole.
I'm really just to verify that this is normal. The nature of such a device just might be noisier than what I expected.
Please send a video over to email@example.com so I can check out what you're experiencing! It does sound like it's louder than normal.
