Let me start by saying I know nothing about electronics and technical specs. But I'm eager to learn.
I have a new Tobias and I've noticed a buzzing and hissing that is present when I'm not playing any notes. It only goes away when I turn the bass volume knob all the way down. Didn't notice it too much until I started practicing with earphones--then it really becomes prominent. I played a show recently and when the sound guy put me through the board it really became apparent that, "Houston, we have a problem"
At first I thought it was the amp, but then I plugged another bass into my amp and there was no problem.
What do you think is the most likely cause? I'm really hoping I can find a solution that doesn't cost me an arm and a leg. I'd appreciate any advice anyone has.
