when did pick ups come out? and when did they get popular amongst jazz musicians? I noticed that most of my jazz albums are from about early 50's to mid 60's, and I like the way they were recorded. I have albums from the 70's and 80's but it seems like a lot of the guys at that time decided to record using the pick up signal only. I wonder if pick ups became very popular and guys just weren't mic-ing their basses anymore... I like Ron Carter's old sound, like on Miles second quintet. then in the late 60's Dave Holland started playing with Miles davis, and I wonder if he was already relying on pick up for his sound.
