Hi Kinya, lately I'm playing and modding my special 20. I think that they have nothing less than a crossover, but I'm dealing with and issue: the plates and the combs create some leaky spots near the edge of the reedplate. It's not a problem on the back, but on the left side, when tongue blocking there Is a massive air leakage (see attached photo https://ibb.co/1mRwR6r ).

How do you usually deal with this? How do you seal these spots?

 

TIA

Hello Tia, the trick is

Hello Tia, the trick is always to have the flattest reed plates marry up to a flat comb. Although my recent posting was regarding a bowed BLOW Plate on a Marine Band Crossover, the operating principles are the same. 

Please review:

then get back to me with your results ...

If you found your BLOW Reed Plates are super flat:

  1. swap out the SP20 comb with another SP20 comb that you know seals well
  2. contact Tom Halchak at Bluemoon Harmonicas <info@BlueMoonHarmonicas.com> https://bluemoonharmonicas.com/collections/hohner-special-20 He'll hook you up with the best fitting Special 20 combs available

Your HARPSMITH, Kinya

Tom Halchak's Blue Moon Combs

I second that emotion re Tom's combs. Not only cool colors and nicely milled, but also with beveled holes, like the Rocket combs. Well worth it.
