Topic: The "New String" Effect
I put a new set of D'Addario NYXL's on my Les Paul last evening, and was listening to the change in tone it made afterwards. Unlike an acoustic guitar, the magnetic reaction is what makes the sound, not the string itself vibrating and reverberating with the guitar's body.
For this reason, the only thing I could notice was a wee improvement in sustain, but little else. When new strings are put on an acoustic, it almost sounds like a new guitar ... much more noticeable.
I will say that the Grover 106 locking tuners make string changing so incredibly easy, and the NYXL strings do stay in tune better than anything else I've used, especially on a guitar with a tremolo or if you do lots of bending.
Just some observations ...
