I can’t believe it ….I’m 67 yrs old …bought my first harp in 1969 when I was 11 …… I’m just learning there are “ High Tuned “ harmonicas out there . I know of all others like Country tuned and such . But where have you been hiding High Tuned . All searches lead me to a dead end and High G only . Who makes them ?? Where can I get them ??
Educate me please !!!
The Seydel 1847 Classic is available in HG (high G), HAb (high Ab), HA and HBb.
There is no additional charge for these “exotics”.

They’ve even got a little sound file to listen to.
Who in the States sells them ? Shipping from overseas could triple the price
Edit : Found it
Lee Oskar makes them too and they are half price.

Thank you @Dai
@dai Seems Seydel is the only one who offers 4 different keys . All others only offer the one key / High G
Examples of where they would be used?

That’s a great question / thought / discussion …. anyone ?
Where ever you desire. 
Many people use them because they are more easily heard above the rest of the band: the higher pitch makes them stand out better than the lower versions (especially for high G vs. normal G, but even for the others as well). Some country musicians prefer them, but really it is a personal choice – often to just get an alternate sound.
What is sometimes done is to play both a “normal” and its “high” version during a song for additional impact or effect. In other words, don’t look for “rules” – go with your instincts and desired effects during a performance. 
YES !
@thunder58 I think everyone makes High G? I have a Lee Oskar for it.
@robertchartrand2104 Can’t say I use it a ton, but in a full band sometimes a regular G doesn’t really cut thru the mix, so a high G can be helpful in those situations. For example sitting in with a band on Sweet Home Alabama it could be cool, although I like playing a C contry-tuned harmonica in 3rd position major in that particular context. But dense mix key of D, High G harmonica can be great.
Suzuki Manji 10 hole Diatonic Harmonica M-20 makes High G
I own a High G Lee Oskar and I use it for playing songs like “Up Around the Bend” by CCR where I want my harp solos to be heard over the PA. I actually prefer the higher keys over lower ones myself (unpopular opinion, I know) because they have powerful wails whenever I’m playing the blues on them. I know the more shrill sounding upper register of these harps aren’t for everybody, but these harps come in handy when playing gigs with a loud band.
@Luke Here’s all the models I could find on Rockin’ Ron’s and Harmonicaland USA that have at least a High G.
Hohner: Special 20 and Marine Band 1896
Seydel: 1847 Classic/Noble (up to High Bb)
Suzuki: All of their pro-grade models except for the Bluesmaster and the Just Intonation version of the Fabulous (not counting harps that have been discontinued)
Tombo: Major Boy/Lee Oskar Classic
Harmo (in house brand for Harmonicaland USA): Rover
DaBell (South Korean manufacturer): All diatonic models
Kongsheng: Mars, Solist, Bluebird, and Sunrise
I also checked on Amazon for finding JDR and Easttop models if they have anything in high G, but they don’t. I’m not sure about Yonberg either since Rockin’ Ron’s is almost completely sold out of them.
just a side note :
Rockin Ron no longer deals with Easttop
Yonberg is now selling harps with either brass or stainless steel reeds. However, they only list “G” and not “High G” in the list of available keys – so I guess they do not offer “High G”.
