I tried 4 different string sets on a new jazz 5 clone bass. I was going for a half-wound / pressure wound string. the ghs pressure wounds were the only string set that provided the same sustain on the B string and even starting out the B was a little less sustain, but I could compensate with active electronics. so I 'settled' for those strings because they were closest to consistent across all strings. It's true about every bass needs to match its strings, as I had never had any B string issue with 2 other 5'ers. So I played it a while and in a few weeks I went back to another bass that had the tone I really wanted. And I'd pick the new bass up once in a while and play and then put it back. Last weekend I took out the new bass and thought about trying out a few other string sets. It had been a few months and the pressure wounds didn't seem to be aging all that well. I bumped a tuner getting it out of the gig bag and brought out the tuner. The strings had stretched (or ?) and were off a full step. I tuned it up and quite unexpectedly everything came to life. Now I love these strings. They are so responsive to producing different tomes based on where and how they're played and have a much wider tonal response than any of my 'favorite' strings. These things are great.
