Anyone ever have any luck with an acoustic/elect. bender?

I was wondering if anyone had ever had any luck with an acoustic electric guitar with a B-Bender? Some years back I put a Palm Pedal on an Epiphone acoustic/electric dreadnought and messed around with it some at the house and was really enjoying the thing. I took it to a gig to do some tunes on it but the movement of the unit came through the amp pretty loud so it was really useless. I guess it'd be OK to use it through a mike unplugged. When I got my P/W bender installed at Stringpull's shop he had an old Martin dreadnought with the acoustic version of a P/W bender in it. I didn't think to ask, but would one of those be noiseless if plugged in or does anyone know of another bender that would work on a plugged in acoustic? Maybe a Higgins?.....Thanks, JH in Va.

However it has a really short throw...which you may or may not like. I have one that I would part with if your interested...
