I use it for 2 years
excellent sound in spite of the fact that it is a microphone placed in the bridge.
(Not a system that piezo)
no problem of feedback
impractical to use with the Schertler prampli.
excellent quality price.
unless you want a true acoustic sound made by the system of the same brand of tablet
I would do the same choice if c'tait again.
I use it since 4 years ago I was playing on a sensor Fishman (150).
Report qualitprix honnte, nothing more. It's been almost 400 even when the sensor!
With exprience, I do it again this election.
Advantages: very good sound, finally finished the sound of "soft trumpet" of some electric violins and sound sensors nazillard pizo classics Fishman.
If I understand correctly, this sensor consists of a condenser microphone encapsulated in a "plug" of stem. I place not in the bridge but as Counsel in the eye of Oues, I found the sound better there.
Edit 18/11/2009: I changed the position and handed the position indicated: in oue sound is nice, sure, but certain notes stand out much more than others, which is very sgnant
on the other hand since I have a Focusrite VoiceMasterPro behind, including d-esser and switched rings ...
In addition, the output level is consquent and therefore much easier to work on a rack of effects.
Sanding should be the liege to fit the violin, but nothing irrcuprable: if we get stuck (or if you change the violin), a layer of varnish over and over again!
Inconvnients: no empty sand the liege (on and off the bridge!) To fit perfectly on the violin, but at least it's tailor-made!
