Anybody got some experience with one of these devices?
A bit. I used and endorsed them for a few years and fitted a dozen or so for other people.
Positive, or not so positive feedback? Pros/Cons etc
They are on the brighter side of these things - quite brittle sounding, percussive and "quacky". On the plus side, this helps them cut through in a louder, rockier setting.
The piezos in the Fishman saddles often break and the saddles have to be replaced - I learned always to have a stock of spares. Eventually I changed the saddles for the Graph Tech Ghost saddles (also partly for the 13-pin hexaphonic output) and have never looked back. I still have the Wilkinson made bridge though - just changed the saddles and electronics. Graph Tech also have a much wider range of saddles and bridges.
