Only one gig so far, Marc, with the second coming up on Friday.
First thing to note is that I thought I'd allowed plenty of time for these strings to settle to pitch - big mistake! For the first 10 days I was tuning back up a semitone at least twice a day to keep it honest. By the night of the gig they had finally settled and I relaxed, but I then discovered that playing three sets of rockabilly is really quite different from occasionally checking the tuning.
I must have checked & corrected the tuning at least a dozen times during that gig. My blushes were spared by the inebriated state of the guitarist, whose own tuning issues did an excellent job of disguising mine.
Next, the difference between very-well-played-in Silver Slaps and brand-new coated guts should not be underestimated. The gig was seriously hard work, and my fingers were aching mercilessly long before the end.
Finally, I loved the tone and I have every expectation that these strings are going to settle in wonderfully over time.
Cancellations allowing, I'll be gigging this bass every weekend for the next 12 weeks. More to come ...
