My store is not taking any orders today due to health reasons which limit to my productivity.

My custom harmonicas, combs and tools are made to order. If items are out of stock on my website, it's likely due to my workload is at the limit. Please see my dealers for all items I offer.
Maximum production times may be up to 16 business days for combs and tools. Current production time for custom harmonicas are shown on the top of the custom page.
Thanks for your support.

7 Limit Just Intonation is when all the notes of the draw plate are in harmony.
The recipe to achieve this is laid out as a table of offsets but you cannot tune a harp to be in harmony using only numbers. No tuner is accurate enough - not to mention because of our embouchure, we skew the offset when we play individual notes.
This video is pretty much an audio-only example of what 7-Limit Just Intonation tuning is.
7-Limit-Just-Intonation favors the major chords over tuning the single notes. Any three consecutive holes played on the blow plate will play a major chord. Any three consecutive notes played on the draw side will play major chord tones but anything above hole five will include the flat-seventh and/or ninth. When tuned to 7-limit-Just Intonation, these chord tones are in harmony and imply the tonic.
You can call it a harmonic, a difference tone or a combination tone. When the frequencies line up perfectly, the effect is that the sum is greater than its parts. You get a louder more powerful sound.
