I like Sheldon's strings a lot. I rotate through two sets at once per bass. One set on the bass, the other soaking in denatured alcohol until I need to switch them out. I've been running on my Voodooooozeeebra for over 2 years with the same two sets.
I am reading this post with some degree of uncertainty, I have been in this game for many many years and I once met James How (RIP) former owner of the Rotosound Strings company at a music show and was able to ask him a few questions about strings, construction methods, and their longevity, I have learnt from him that once a set of strings has "had it" there's no method you could use to refurbish them. Yes you can keep them in a denaturated alcohol solution to remove the grime and sweath from within the core to the wrappings but what you could never do is repair the damage done to the strings by fretting, slapping, and the effect caused by extended tension whereby the core and the wrapping loose their round shape turning the string into and oval or elliptical shape. Now when that occurrs the harmonic response of a string is no longer accurate, a fret scored or oval string will no longer ring like it should hence tuning and pitch will never be accurate again, if you accept this then you will see that "washing" the strings would be only a short term solution, that might well give you a similar sound to that of a fresh string but not for very long and I believe tuning would give an inaccurate pitch not on an open string but fretted.
I can't believe how people like Ed Friedland to name one, say they play a Precision with a 10 years old set of LaBella flats to get that James Jamerson vibe, it's begger's belief as to how his strings hold tuning after such a long time. Strings are consumable like... oil in your engine or your brake pads, you just can't run them past their worn stage.
Sheldon what is your view on worn strings?
