hi,

this several I was go to Violin several place.

1. CMC Horn Mouth making factory because I had some solid Fine ebony & Solid Fine Sand Billy wood On hand. I cal this factory made solid horn mouth already. But I got one new material that was C37 similar Violin Vanish.

C37 was very expensive in Europe.

This pair was special version because was use C37 similar material Volin Vanish treatment already.

C37 violin Vanish, was famous in internet & most speaker user ( Most was full range user) was use this paint for its speaker driver cone. ( U can see lowther & AER in internet)
For OPT now I saw two brand in Interent was Audionote & Audio-consulting now is using in their products.

I was interested for this so I research for this data & found Newsday most ( over 95% low, Mid & mid-high level small violin, Cello was MADE IN CHINA. Most Famous factory in China such as Benjing to buy this vanish. The told me that this vanish was separated into Oil base, Oil + methyl Alcoholic base.

C37 similar volin vanish was made by extract of Shellac (Lakeh), Resin, frankincense, Commiphora Myrrha ,Myrrha, Olibanum Plant base) etc Natural extract, pre-heat to Estimate temperature to form UP! This Natural Extract will seperate alcoholic base or Oil base. Most Volin was use Oil base but need longer time to dry up. Alcoholic base will offer U easy to increase or decrease( use alcoholic to be a Solvent ) to remove excess paint. So I choose Alcoholic Base & half Oil + Alcoholic base back to test & coating into solid wood horn & compare the sound performace about them.( with or Without C37 similar violin vanish piant.)
Also this C37 for user that he can paint by themselves. ( standard was 5 layers).

Take a look for the C37 similar paint fine ebony horn mouth.

Now is send to one of my friend test with TAD TD-4001.

If this C37 similar test will good performace. diyers will had cheap products to use, not need to suffer with expensive material.

thx
