Taylor ES1 vs KNA SG-1 Acoustic Guitar Pickup Comparison

This is just my experiment on acoustic guitar pickups.  I installed a KNA SG-1 piezo pickup on my Taylor 214ce.  This Taylor guitar is has a built-in ES1 pickup.  The latest generation this guitars have ES2 or Expression System 2.  I then recorded both outputs of these pickup on Zoom Q8 mic inputs.  Checkout the video and hear the results of this comparison.
