[LAU] Very low input from accoustic guitar pickup

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.

Best regards,
Sebastian.
