Improving on a Good Thing

Monster Harmonica Workbench

Last issue I reviewed the Seydel Blues Soloist Pro Harmonica (#11301A @ $35.95). Readers will remember that I was not satisfied that this instrument was living up to its potential.

This month I'll begin work on "customizing" the Blues Soloist Pro. Numerous proven strategies will be applied in an attempt to create my next favorite harp.

For new readers, please refer to past issues of Harmonica Sessions, Monster Harmonica Workshop for a listing of required tools and recommended set up techniques.

Sizing (a.k.a. Embossing)
A term, I believe originally coined by Master Harmonica Craftsman Pat Missin, is a technique of "shrinking" the size of the reed plate slots. Reducing the tolerance surrounding the reed will minimize air leakage, increase compression, and enable the player to achieve extraordinary volume with less effort.

	Notice the amount of light that is shining through the gaps surrounding the reed before the sizing technique is applied.
	Utilizing the handle end of a pair of tweezers, apply slight pressure and gently stroke the entire length of the reed slot in a back and forth motion. Due to the radius of the tweezers handle, the reed will be pushed into the slot as you make your way toward the rivet end of the reed. This will limit sizing to approximately 90% of the reed slot. Not sizing the last 10% will be negligible. (Tip: almost any small radius implement will work well as a sizing tool, for example, the ball end handle of a tuning fork, a socket, etc.)
	The reduction of light surrounding the reed after the sizing process is significantly less.

My modification of the tip scooping technique is to machine crescent-shaped divots into the tip of the reed slot. This technique turbo charges the air directly underneath the free end of the reed where there is the most leverage. Another strategy that will lead us towards harmonica bliss!

This technique incorporates both setting the reed curvature and calibrating the gap (offset). Mastering these techniques will perfectly match your playing style to your harmonica; thereby, giving you the sensation of playing an instrument that was built personally for you.

Sectioning the reed into thirds is an excellent strategy for ensuring a methodical approach to reed curling. The reed plinking tool (modified feeler gauge) on the left raises the free end of the reed and applies pressure to the apex of the curve (try visualizing a saber striking an opponent during a fencing match-see the curvature?) The brass stock shown on the right, gently massages (locks in) the curvature into the reed.

Refer to the "The Tao of Harmonica Customizing" April 2004 issue for detailed instruction on Reed Curling and Gapping.

I hate to do this to you, but this issue is going to end as a cliffhanger. Stay tuned 'til our next issue of Monster Harmonica Workbench when I will publish the results of this harmonica-customizing jamboree...
