›››enlarge	Using an idea based on a comb devised by Will Scarlett , Hohner USA's harmonica technician, Rick Epping, has invented a totally new Diatonic Harmonica.
›››enlarge	Naming it the XB-40 (XB=Extreme Bending) Hohner originally introduced it in spring 2003 at Frankfurt Music Fair.
›››enlarge	At first bending the dual reed system needs no valves at all. The reason for a weak response in a non-valved Richter harmonica is air-loss among the silent reeds - meaning breathed-out air leaks through the gaps of the draw-reeds and breathed-in air leaks through the gaps of the blow-reeds.
›››enlarge	The XB-40 solves this problem with two elegant design features: First of all, an internal valve chamber system has been introduced, which totally isolates the draw-reeds from the blow-reeds , making any escape of air through the silent reeds impossible.
›››enlarge	Secondly, the auxiliary reeds that enable the bending of the notes have a zero-gap, which stops air-leakage almost entirely, producing an increased response never before possible in a standard harp.
The sound of the XB-40 is as extraordinary as its bending abilities. The dimensions of a normal diatonic harmonica impose a narrow limit to the maximum size of the reed chambers. The resonance frequencies of the chambers in its middle and lower register are too high to allow the reeds to vibrate at their full potential. However, the increased dimensions of the reed chambers in the middle and lower register of the XB-40 allows a full, dynamic sound to be produced. In addition to all this, the XB-40 creates a volume of sound never before possible on a diatonic or chromatic harmonica. Its larger reed chambers, (including the inter-valve chambers) amplify the sound of the reeds to a degree that hitherto was impossible on a normal diatonic harmonica. At the same time the new mouthpiece provides an increase in volume by increasing the airflow to the reeds. A two-piece injection-moulded comb allows easy access to the valves and reed chambers for cleaning and maintenance purposes. Reed plates are attached to the comb with screws, providing easy dismantling for maintenance and reed replacement. Valves are fastened at the inside of the comb instead on the surface of the reed plates, which supports easy tuning and adjusting of the reeds.
The XB-40 is available in all keys except Db. Remarkable in this context: key of C is highest an Low D is the lowest key.
