I play the 45-125, here are the part numbers that include the tapered, B and E strings. I typically order them five sets at a time to buy in bulk directly from SIT, as I have not found them for sale by this part number anywhere else.
- TNR545125L (45-125)
- TNR550130L (50-130)
I also used to play the Sadowsky’s and Skjold strings before that, all with tapered B&E strings.
I find that a tapered B string has a huge impact on the clarity of the tone on a B string. They don’t thud like regular strings can sometimes do. There’s a reason that many of the high-end boutique builders use tapered B&E strings and that’s for low action and clarity.
When I hear someone say that a bass has a terrible B string, I ask if they’re playing a tapered B because that makes a huge difference in tone.
The tapered strings also give you the ability to have much lower action with no buzzing as well. So when I get a new bass, that’s the first thing I do is put my strings on it and do a setup with low action.
