I posted this under 'strings' but got zero response so I'm hoping to make it a bit more visible in the Jazz section. Any comments most gratefully received. I've read some TB posts that mention the beneficial effects of detuning , slackening, whatever, strings that when they are retuned to pitch give a new brighter sound. This accords with my recent experience. After a few days that new brightness seems to fade away. Do any of you do this routinely, between gigs, once a month, whatever, to maintain the brightness? I'd be very interested to know.
