Double Reed Special 20 with Aluminum Comb

  • 17495

Important Announcement

Effective April 17, 2017, I will take a break from building harmonicas to order.  Blue Moon Harmonicas is not a giant company with 100’s of employees.  It is one guy, in Clearwater, FL, building harps, one at a time, as they are ordered by you - my customer.  Summer is rapidly approaching.  The kids will be out of school.  We’ve got some trips and vacations planned.  I am already backed up with orders for harmonicas.  It will take me a month to get caught up as it is.  I see no point in allowing customers to design and purchase harmonicas when I know that I won’t have time to build them until August or September.    I apologize if this has caught you off guard.  If you have already placed an order prior to today, fear not, it will be built and shipped within the next 3-4 weeks.

Custom Combs are Available for Immediate Delivery
This break does not apply to Custom Combs.  I have 100’s of custom combs in stock.  They are prepped and ready for immediate delivery.

Harmonica Kits

I will begin offering Harmonica Kits within the next couple of days.  If you want a Hohner Harmonica, a Harmonica Kit will consist of your choice of a Custom Comb and a New Harmonica.  If you want a Suzuki, you will receive a Custom Comb, a set of Reed Plates and a set of Covers.  I buy complete harps from Hohner. I buy individual components from Suzuki. 

Along with the Harmonica Kits, I will also post some How-To Videos on YouTube which will provide instructions about how to do some basic work on the Reed Plates.  This will include:

  • Flat Sanding the Draw Plate
  • Gapping the Reeds and Adjusting the Profile
  • Tuning

These things are fairly simple and greatly improve the responsiveness and tone of the harmonica.

Ready-to-Go Custom Harmonicas

Lastly, I will be offering small batches of “Ready-to-Go” Custom Harmonicas.  I will offer 10-15-20 harps at a time.  The “Bad News” is that you will not have the ability to choose the Custom Comb but the “Good News” is that they will be ready for immediate delivery.  No waiting!  I will post announcements on Facebook, Modern Blues Harmonica and harp-l when another batch of Ready-to-Go harps is available.

Thanks for your support.  Thanks for understanding that we all need a break every now and then.

Blue Moon Double Reed Special 20
with an Anodized Aluminum Comb

The Blue Moon Special 20 is built with one of our CNC Milled Anodized Aluminum Combs and Hohner Special 20 Reed Plates & Covers. We then add an extra plate (essentially a reed plate without reeds) and a Blue Moon Special 20 comb that has been custom designed to accommodate the thicker plates. The extra plates are mounted on top of the blow plate and between the draw plate and the comb to create reed plates that are thicker than stock Special 20 reed plates (not quite twice as thick). The principle behind this design is that the Double Reed Plates create larger chambers in the reed slots. Therefore each time a reed swings through the slot it will move more air than as compared to a standard reed plate. The result is increased volume and responsiveness.

At present we have two Anodized Aluminum Combs to choose from:

  • Black Anodized Aluminum
  • Clear Anodized Aluminum

You can choose from either a Clear Anodized Aluminum Comb or a Black Anodized Aluminum Comb. We use 6061 Aircraft Grade Aluminum. Anodization is an electrolytic process whereby a layer of Aluminum Oxide is created on the surface of the metal. Aluminum Oxide is non-reactive and more durable than aluminum.

Keys Available = G, Ab, A, Bb & C

The following work will be done to this harp to improve the performance:

  • Installation of Custom Blue Moon Comb
  • Flat Sand Draw Plate - Flatter Reed Plates + Flatter Combs = More Airtight Harp
  • Gaps Adjusted for optimal response
  • Reed Shape checked and corrected if necessary
  • Reed Plates Tuned to Modern Compromise Temperament @ A=442Hz
  • Back of Cover Plates Opened (See Pictures)
  • Cover Brace Installed (See Pictures)

As always, your satisfaction is guaranteed. If you are not completely satisfied with this harp, speak up, let us know, and we'll make it right, either by fixing this harp, replacing it or giving you a complete refund your call.
