Big tone Piezo pickup

The Big Tone pickup is a workhorse in the gypsy jazz world.  The piezo element installs discretely in the bridge of the guitar with a wire running through a hole in the soundboard under the treble foot of the bridge.  The wire is soldered to a 1/4" output jack at the tailpiece of the guitar.  This system doesn't have any batteries or on board controls and offers a simple, reliable option for sound reinforcement that is minimally invasive.  The tone of the pickup is clean and clear, well balanced and has plenty of headroom before feedback.
