i have not installed it yet. i understand it might require opening the tailpiece slot/hole a little. standard size?

I already own a stradpet-bridge that fits and sounds very good on a sojing-electric-violin without changing anything at the bridge. On the electric-violin it sounds better than the wooden bridge and has a good and direct sound-response. Because I have a second sojing-electric-violin with a much to high bridge from the fabric I ordered stradpet-bridges for this violin and some more on reserve. On my acoustic-violin it is a bit to high and it sounds a bit more artificial than a wooden bridge but it's alright. For my violin-builder it would be more difficult to adjust the carbon-bridge in highness and size for good fitting because of the hard material. But it would be possible he told me. I keep the carbon-bridge in my violin-case as a second bridge.
When my wooden bridge isn't good any more my violin-buillder can adjust the stradpet-bridge on it.
Other stradpet-bridges I'll use perhaps for pupils-violins or restauration-projects.
The price is very cheap for such a good quality! Looks like it is very longlasting and once adjusted at your violin it will never get rotten or break down. Even the sharp E-string can do no damage to it. I'm almost sure the stradpet-bridge will last your and your violins life forever! On acoustic violins I prefer a little bit more the sound of wooden bridges, but the durability and high reliability is a big advantage! On electric-violins where the bridge can be changed the stradpet-bridge is the best solution (when the transducer/pickup-system is under the bridge). The design looks great especially on electric-violins but also nice on acoustic violins. Perhaps classic-style or orchestra-players would prefer a carbon-bridge in wooden colour and style. Perhaps stradpet could offer it also in a more classic/wooden design. I'm a professional violin player and teacher, like folk & rock, also on my acoustic-violin is a pickup installed. I like the black design. Should also be no problem, installing a pickup at the stradpet-bridge like the fishman V200 or similar systems.
Hope my review is helpful for other violin-players!

Excellent product. Makes the sound better. I'm satisfied.

As always - perfect !

They are beautiful, and my sound tests clearly show that they improve the response and openness of tone.

The titanium tailgut is soft but very resistent. It do not enter on all the tailpieces but nothing anormal with the descriptions, Stradpet always offers suggestions to install it. A very recomendable product!
