Old tyme tuning would be factory tuned, machine made reeds. Play them for a few years, a few go out of tune, and alas! Old tyme sound.

Speaking of unique tunings, especially as they relate to zydeco played on Cajun boxes, a very close associate of mine that builds very well known Louisiana boxes that feature clever graphics of "lobsters" on the bellows, told me that "Sloppy Wet" tuning is the next "in" thing for zydeco. It's what Keith Frank has asked this (name withheld) builder to install in his accordion. The reeds are from Czech Republic, ordered by the set, and installed "as is." No hand-tuning -- and these are #3 reeds to boot.

This may have been the opinion of (anonymous builder), but usually what Keith Frank likes, the rest of the zydeco world emulates.

You didn't hear it from me on this forum... just hide and watch...
