To start with I'm offering one famous chromatic brand and model as the base harmonica for this revolutionary new instrument: the popular, user-friendly Hohner CX-12. This is one of the cleverest harmonicas ever designed, with convenient snap-fit construction. It makes assembly/disassembly of the THS DoubleChrom a breeze - as you can see from the video below.
There are many colours of upper unit available and a range of keys, all in traditional chromatic Solo tuning. To save money you can just buy the upper slider-mouthpiece and lower enclosure. You can then insert your own CX-12 rear units and sliders. (However, this option will not give you the bespoke laser-cut rear sliders and slider-locking bar, as seen on the video).
For over a century, the only way chromatic harmonica players could play octaves was with 'splits': using the tongue as a divider and playing through both sides of the mouth on a standard chromatic. It sounds great, but is hard to do with real consistency and accuracy, especially at speed. No longer: my BlowThru OctaChroms make chromatic octave playing a breeze! There are two types: the standard OctaChrom and the amazing OctaChrom Selectable. Watch the video to see and hear them in action.
Please note: You'll be fitting standard C reedplates and Tenor or Low C reedplates. The normal C reedplates must be at the front and the Low C reedplates at the rear, or the OctaChroms will not play well.
In addition to the ten reedplate screws, I also supply four small coverplate screws for the rear covers of the OctaChrom Selectable, which screw directly into the comb.
