Put a humbucker in the sound hole :: Yamaha APX500III [4.7 lbs]
A player brought by his custom made humbucker sound hole mount and wanted me to re-install it for him. It was previously mounted but missing the screws and not wired up. The guitar does have an undersaddle pickup, but the wire was broken free from the pickup. I disconnected the side-mounted preamp and ran the new humbucker pickup directly out to the jack.
