Hello bassic fruitcakes! (including me) The more I play bass and the more expensive, very well-sounding basses I play, the more I like passive. Why? Let me explain... in the passive basses, there's more left of the natural sound of the bass itself. It isn't modified by some stupidity that calls itself pre-amp (whether it is a very good one or not, I doubt both gadgets) so the sound gets tiny and less natural. Ok.. I have to admit... when I turn it ON, I sometimes get crushed by the enormous power out of this 9V device, but does it really make it better? Then...compensate the volume-loss and trie again passive. Will you go back to active then? No way! (E.g.: A man doesn't gain more character, going to the fitness-palace around the corner eh? Or is a woman more woman with bigger breasts... well alright, we can talk about that.
