[Harp-L] question about tuning a harp

[yumpin_yimminie@xxxxxxxxxxxxx]

I've got some tuning that needs to get done.  Have been curious about how it is done at a factory or at a customizer.  When I go through this I end up assembling and disassembling a lot.  I mean a whole lot.  I mean so often that I try to ignore the out of tune-ness until it can't be ignored anymore.  

But surely at factories or customizers they don't actually assemble the harmonicas and blow into them to find if they are in tune.  

Would appreciate if someone(s) could fill me in on the how it is done quickly.

Thanks much!

Have a Great Day,
Jim
