The idea of combining two 10-hole harps behind a single mouthpiece is not new - but it's not easy to get good reed response, and has never been done convincingly before. That's all changed! After intensive R&D over the past couple of years, I've come up with a quick-change assembly that really works. I'm now releasing my ground-breaking Twin-Diatonic harps in a range of exciting options - check out the two videos to see and hear them all in action.
An obvious choice is to make 8 of the bends the same as on stock harps (which only has 8 bendable notes), and the rest to go down a semitone. This gives a fully chromatic harp with bends alone, plus lots of cool 'bend enharmonics': notes you can get two ways, bending or non-bending. Another way is to tune the x-reed so the bends go down to the next note of the home scale, whatever that is. It's very expressive - I demonstrate a Solo tuned version in the video.
Using my combs and valves with the TwinDiatonics will ensure they work to their best. Good reed gapping and slot embossing will always help too, though valving makes these aspects less important than they are on un-valved harps.
This is just an introduction to these exciting new harps. Individual pages with dedicated videos for each type, as well as ordering options, will be up around 20th September.
While you can just buy the front unit to assemble your own OctaHarp using stock combs, trying to fit single valves to combs not designed for them can be tricky and frustrating. Adding my specially-designed PowerCombs and Stealth-Valves to your order will simplify and speed up the process of making an OctaHarp that sounds great straight away. They are available at half-price when ordered for the TwinDiatonic harps. Watch the videos to see how the valving is done, and all the parts fit together:
All TwinDiatonics are made to order. That allows you to choose from a big range of keys, colours, brands, tunings and other special features. Once we get your order we make the bespoke parts in our workshop and order the harmonicas you've chosen. We then either post to you (DIY option below) or to the Recommended Customser you've selected. Here's how the two options work:
All TwinDiatonics sent with tracked international shipping (included in the overall price).
The Easttop version comes with the lowest cost of the harmonicas but has excellent playability and durability, because of the good basic quality of their parts. It allows me to do high-level custom harmonicas at a low price. The Suzuki version has a higher basic cost of the parts, but comes with the Suzuki reputation for quality manufacture and great reed life. I take quality very seriously. My custom Easttop and Suzuki TwinDiatonic models may be returned unconditionally within 2 weeks of receipt if you are not satisfied. All reeds are warranted against failure for five years. Reed plates have engraving date customization.
WARNING: My custom harmonicas are works of precision. Unqualified adjustments or attempted modifications may destroy the tuning or the entire instrument.
