i have heard that vintage instruments are very good compared to todays modern stuff. Q1: why do vintage instruments sound better in terms of tone compared to todays modern active circuits? Q2: how would a 70s precision compare to an Ernie Ball sub? [both passive] Q3: how would a 70s precision compare to my current yamaha bbg4sii? [which has active pickups and preamp] im asking because im about to buy a new bass and i want to make the right choice. and i still have a zillion questions for later on as i continue to learn. Thanks.
