Jon (or anyone), this Axis Sport w/MM90's & piezo bridge I picked up off Ebay sounds absolutely delicious. The piezo pickups, however, have nowhere near the clarity nor acoustic guitar character of the JP6 w/piezo I played in SLO. This guitar doesn't have the separate piezo module like the current models I saw. Was there a change in the preamp that occurred after this particular guitar was produced, or does this indicate some sort of other issue? Thanks, sir (or whomever)!
