Tony, thanks for sharing this hard-earned wisdom about harmonica cases. Storage, transportation and quick and easy on stage access to our collection of harmonicas have been an age-old problems that all harmonics players wrestle with. It looks like you finally have a solution that fits your needs.Since 2008 I've been writing a column for Harmonica World magazine. The initial brief was to write about tuition, the scope has since expanded to anything harmonica related. I'm now putting some online. The one below is about harmonica cases, and how it took me 30 years to organise them properly.
