Thank you very much, that was illuminating.
However for now I'm was looking for a simplistic solution without the slightest care for sound quality, as I'm just using the signal to take its envelope in order to detect knocks and the like.
But now I know why it sounds the way it sounds and that with an appropriate high impedance buffer stage it can sound way better, the day I'll need it :D
