I've talked a lot this weekend with my guitarist about woods, neck woods and neck thickness. About tone, about taking your bass out of it's case so it can pick up all vibrations in the room, etc etc. But, there is also one major difference between the old and new basses. The pickup selector switch. In the '70s it was placed on the lower horn of the bass, and the space between the neck pickup and the neck itself was a lot smaller these days. So, you were forced to thump and pluck between the neck and bridge pickup. Well, I did the same on my '98 series I/II and voila, there it was, the good old buttery sound. Try it.
For me it works perfect, it's pretty hard to do but just like the old basses, you have to get used to it to make it work.
