Fwd: RE: [Harp-L] xb-40 tune-up - another possibility

Laurent - 

The link you sent doesn't work, because of the period at the end of 
the sentence, which became part of the link. Cut and past the text 
somehwere else, remove the period, then paste the link into your 
browser in order to access the referenced page:

http://www.planetharmonica.com/ph5/VE/XB_40HighNotesUK.htm

Anyway, the problem that Rick Epping describes on that page is only 
on C and high D XB-40s, not for lower harps like A. I know, as I have 
experienced the C-harp problems. For me it was not squealing but 
pitch flattening and poor tonal response.

I don't think the problems Paul is experiencing on his A-harp can be 
ascribed the trouble occuring with C and D XB-40s. It may be a 
question of technique, or it could be something the wax fix could 
help with.

Other possibilities:

--- One thing I have experienced with XB-40s is the ease with which 
you can over-stimulate the reed, so that its response begins to 
distort (and not in a good way). I find I have to temper my attack to 
account for thsi sensitivity.

--- One of my XB-40s does have a reed that makes an unpleasant sound 
when I bend it. I'm pretty sure from the sound of it that the reed is 
hitting the wall of the slot, probably due to a burr on the edge of 
the reed. If I'm right about the cause - and Paul's problem might 
have the same cause - then sliding something like an extremely thin 
metal feeler gauge between the reed and the slot edge could be used 
to remove the burr and clean up the sound of the reed vibrating.

Hello Paul

I'm not sure if you already know, but the squealing on high bends is 
partly
due to the harp design. You can find more info by Rick Epping (the XB
designer) on 
http://www.planetharmonica.com/ph5/VE/XB_40HighNotesUK.htm.
This info was first sent to harp-l and reproduced on planet harmonica 
with
Rick's agreement as part of a global article on harmonicas based on 
Richter
allowing to play chromatically.

I'm afraid this doesn't fully answer you question but I thought it 
may help
you.

Thanks

Objet : [Harp-L] xb-40 tune-up


Sorry if I'm repeating myself but I purchased an XB-40
a couple of weeks ago and I'm wondering if more
experienced XB users have any setup suggestions
specific to this new type of harp or do I just follow
the process for regular harps.

One problem I definitely want to address is the squeal
I get on some higher draw bends. Is this to be
rectified with the beeswax/nail polish fix. Which reed
should it be applied to; the 'normal' reed or the
auxilliary? Anyone ever micropore one of these?
