Höfner H1133 B Beatle Bass Strings

You will be suprised by how dead-sounding and out of phase the E String will sound once you mount them.
I had these installed by my local music shop, and the owner said to me he felt the E String had a problem, and sounded dim/dead compared to the other strings. So he raised the pickups super high to counter measure, and I though I could work with that…
Well no, to me it just sounds out of phase, like the frequency of the note isn't clearly defined on the initial attack, and then settles with a bit of time.
I asked Thomann's support for comments, providing them with an audio sample, and they came back to me saying they consider the set to be a good one.
So here it is: the sound of the E string is unsuable and disgusting, A-D-G sound just amazing. And now you're left wondering how such a pricy set of strings can be so bad.
What do I do now? Try some labellas and pyramids, hoping for a better outcome.
We'll see!
