fishman power bridge piezo pups????

any of you gearhead/tonejunkies have experience with these things?

i'm wanting to try one of these things out but i don't know anyone who is familiar with them...what are the caveats? tips? tricks?

thanks, as always, for the helpful feedback.

I had one of the tune o matic styles in a godin lg guitar. That guitar had a preamp built on with a volume and 3 band eq. But it sounded pretty good.

I have a nashville power and i am very impressed with the acoustic tone. I also have played around with an lr baggs x bridge in an ibanez artcore with no inboard preamp and it was decent. (no one in the pews complained). I think having the right preamp is more important than type of piezo pickups. Also i have read in the nashville power owners club that some were having issues with individual piezo/saddles dying on them but i have yet to experience that.
