I just bought a set of LaBella Hard Rockin Steel (4 string set). I use to use these strings on my Ken Smith 5 string 3-4 years ago. My question is: Are they making these different. They use to have a Tapered B and E string, but this 4 string set didn't have a tapered E string as in the past.. They feel different and sound more punchier. Even the black silk winding looks different. I had a set of DR Fat Beams on my Jazz bass and these Labella's sounds way more brighter. Just curious if they're using a new method of making these strings. They use to have kind of a QC issue where one string would be dead, but this set are about as bright as D'Addario Prosteel but with more punch.
