[Harp-L] Custom Combs and Slider for the Hohner CX-12

["Brendan Power" <bren@xxxxxxxxxxxxxxxxx>]

The Hohner CX-12 chromatic is a modern classic design, with many great
features. It's my favourite chrom, and I've lovingly hacked it into many
alternate configurations over the years (CX-16, CX-14, CX-10, DoubleChrom).
However it suffers from two main flaws: a loose-fitting slider, and a comb
with over-large air chambers. 

 

The stock slider is not very airtight, and noisy to boot. The comb's large
cavities mean that the highest notes suffer from Helmholtz Resonance
coupling, where the resonant frequency of the mouth/comb chamber clashes
with the pitch of the reed. This flattens the pitch of the highest reeds and
makes them feel unresponsive. I have tackled both issues and created
solutions, which I'm now offering to all who love the CX-12 and want to get
the most out of it. More info here:

Fitting can be done by anyone, but there are a few things to be aware of.
I've made a couple of videos showing what to do:
