Hi, > If it has controls for volume, treble and bass that means it has an > amplifier on board. Maybe the battery is low? > A battery is the proof that you actually have a build-in pre-amp. Therefore you're right: The battery has to be low. >> Pushing the volume to the max also brings noise with it. What kind of noise ? Whitenoise like or a low-frequency noise? >> some kind of impedence adapter If you have a low-freq noise it could be a ground loop or something. In your case, a white noise would come from the fact that you increased the guitarlevel extremly to hear a signal -> Signal to noise ratio != 0 so you increase the noise level as well.
