Then there is the story of Black Sabbath i think on the 'Mob Rules' album where apparently the engineers and Geezer were searching for a specific bass sound, they spent almost a week experimenting in the studio...Geezer was trying different basses and the whole thing was viewed by the rest of the band as a waste of money...Pretty sure Martin Birch was the producer.....Geezer made his sound on Fender basses in the early days but being rather curious and taking who knows what, he liked to try different things.Frankly those stories sound like hooey to me in any sort of current context. I can't imagine a producer saying to someone who plays a Strat with a Floyd Rose that they should play the ES335 sitting in the corner. That's not their sound, and they're not going to play their best on a type of guitar they're not familiar with. Same with basses. If an engineer can't get a good sound without a musician playing a specific type of instrument I'd be wondering if another engineer should be brought in.
As i mentioned Lee Sklar plays lots of basses these days as one example...still the producer usually has quite a bit of say and it depends on the artist and who is paying the bill.
I’m tired of seeing multiscale active 5 string basses on every Instagram suggested video..
