Kind of a dud.
Tried this on my acoustic, tried it on my classical. Barely got a signal through my amp with the volume on ten. Used different cords, different guitars, just won't pickup enough to make it worth the effort. If there's an option to send it back, I'll do that tomorrow. Just got it in the mail a few days ago. I've had transducers before, but this one either is a lemon, or this is not the way to go for me.
