I got these to replace the stock Daddario EXL170s which my bass came with and which stayed on it for about 6 months. I was sceptical at first as I thought the stock strings sounded nicely tamed and aged and not as annoyingly zingy as they were at the beginning. But then I decided to put the NYXLs on and boy did they make a difference! They're tight and punchy and no trace of the annoying zing and finger sounds of the EXLs. What stunned me the most was the B string tone. Deep, tight, powerful, perfectly rounded!
I had a minor problem which turned into an opportunity to asses the real value of the NYXLs. The A string snapped at the ball right away which, well, happens sometimes and I was stupid enough to cut my old strings on taking them off the bass so I bought a new EXL170 set from the local shop as an emergency replacement and when I put the A on, I was able to appreciate the massive difference between the two types of strings and to realise that for the time being, the NYXLs have the exact tone that I'm after. Each time I strum, I'm like, wow, I can't get enough of this sound! I'm curious to see how long the magic will last but I suspect these will come to be my new go-to strings.
Also, kudos to Thomann who were lightning fast in sending me a replacement for the snapped A string so now my bass is all set. Their customer service is second to none.
