I'm toying around with the idea of adding a piezo setup to one of my basses - but how easy/hard or realistic would this be? Is there some were I could buy a bridge that already has a piezo setup? Or would I have to install a piezo pickup(s) into my existing bridge. I'm a little clueless in this area - just how does a piezo setup work and how much electronics (like with the onboard pre) would it need, or does it need a seperate pre? My thought was to have a stacked volume pot, so one level would be the regular volume of the pickups and the other be the volume for the piezo to blend in. I dunno. Is this a foolish idea or is there some relatively easy way to go about it?
