Every once in a while I notice Rutger's bass comes into prominence when I hear several songs by ABBA, especially 'Bang-A-Boomerang' (both ABBA and 'Svenne och Lotta' version), 'What About Livingstone?' and 'Sittting in the Palmtree'.
Given that Rutger has consistently played with Fenders and Hagströms, I'd like to know which bass amplifiers and brands and types of strings he used throughout his career as a bassist. It seems to me that he uses flatwound strings due to the thumpy, but roundish tone, whereas roundwound strings sounds like an ice being crunched to water, which is not something I would hear from several ABBA songs... I'm uncertain about the amplifier since Rutger's gig setup may possibly change over the time...
Feel free to make a speculation on how Rutger got his bass sound
Theres very little out there about him, and even this youtube, looks like he just picked up somebodys Fender and is playing thru who knows what.
If you watch the Abba on concert vids, if thats him playing, theres all kinds of basses being used.
Hard to say, as Tretow and B&B could have heavily edited/produced the bass sound to make it sound tonally different than what he played. I mean by this, turn up the upper mids and pile a bunch of compression on a P-bass track and you can make it sound more like a Rickenbacker.
I've looked and I've never seen much about any equipment used by him, or Janne, or anybody except Benny.
This was something I wished Magnus Palmer would have investigated in his "INcomplete recording" book on Abba. Theres nothing about it. Either he didnt care or didnt bother or nobody would answer, or more likely, only freaks like you and me would be interested LOL
