Ahh! the joy of new strings.
Just put new strings on the banjolin (also dismantled and cleaned throughout). Sounds like new. New strings on this, and on the mandolin just drop straight on and keep tune straightaway, and sound so good. Same when I oil the old flute - good as new.
What about you? Does a good clean and a new set of strings/reeds/pads etc fill you with joy? Or do some instruments take a time to settle and make re-stringing a necessary evil? Do you dread touching your instrument other than to play, in case you upset some delicate balance? Come! Tell us how it goes for you, and we will listen with sympathy and a serious demeanour.
