Dunlop HE904 Hervex Cello Bow Hair, Full Length

My psaltery bow horse hair starting breaking leaving me little to play the instrument with and not sounding so well. I looked for an inexpensive alternative to horse hair and something that might last longer given the psaltery is an occasional use instrument for me. The Hervex synthetic bow hair came up in my searches and the price was right. I bought this one and will probably be able to restring my psaltery bow three times with it. The only pain was threading the new hair though the tiny holes in the wooden psaltery bow. I started out by taking about a third of the hair and making a knot close to the end where all of the hair was glued or melted together. I then applied some UV cured resin to the knot and cured it the little UV light and cut away this portion from the rest of the remaining hair. I think normally you would melt real tree rosin over the knot. To thread the hair through the tiny holes, I used a very small zip tie to try and gather all of the ends together and made an angle cut of the hairs at the tip and was able to thread them through the first hole and snipped of the zip tie to thread the bow up to the knot on the static end of the bow. Then I did the same thing with a zip tie two more times to thread it through the second bow hole, then the tension dowel hole this bow uses. You have to be careful to keep the hair straight and pulled taught while threading as Hervex cannot be heated to make it shrink like real horse hair. Once I had the hair threaded and with even tension (no stragglers appearing loose on the sides), I made a second knot and applied UV resin to it as well. Once constructed, the bow had little if any grab against the strings. The instructions say to use some liquid rosin which I did not have. So, I tried my rosin block, but not much was transferring onto the hairs. After wetting the hair a little and trying to rosin the bow again, I started getting some rosin to take to the hair. After about four or five wet rosin treatments the bow starting sounding great.

Easy to use. Works well, Cello sounds even better with the new hair!

This is synthetic fiber, not horsehair, but is advertised as hair-which it is not. Did not use and returned it.

Besser als jedes Pferdehaar. Ich liebe das Produkt. Schade, dass es so schwer zu bekommen ist.

muy buena calidad lo recomiendo
