SWAN 16 HOLE SW1664 CUSTOMIZATION #7 Reassembly Of Harp David Kettlewell chromatic harmonica

David Kettlewell reassembles the very inexpensive $57 Swan SW1664, as part of a major customization project to create a credible low cost near-pro level harp.
Customizations: Reshaping covers to open them up at the back to improve projection and tonal clarity; sanding top face of comb and underside of mouthpiece to airtighten; smoothing oval hole for mouthpiece screws in the slide so bumpers last longer; lapping of slide to blanks for smoother slide action and improved airtightness; covering covers with gaffer's tape to darken tone.
David's website with many videos and articles is MASTERSOFHARMONICA.COM
His book LOVE OF CHROMATIC HARMONICA...TECHNIQUES AND ADVICE FROM THE WORLD'S BEST! is available in paperback and Kindle on Amazon.

David I've learned an immense amount of information from watching your you tube posts and I appreciate everything about your posts. I purchased a 1664 swan and have found a problem with whole 4 on the lower scale, the blow and draw don't work very well. I live in a small town in Ontario Canada and I have no where to take it to see if it can be repaired. other than returning it to the company, do you have any suggestions? Thanking you in advance John Garton

I called John to explain that player error is often the cause of trouble with hole 3 and 4 on a 16 holer. Try keeping tongue low in mouth, jutt jaw a bit forward, tilt head a bit down, and use the diaphragm. We'll see how it goes.
