Through a little trial and error, I stumbled onto an easier way to "fix" the Spank 2 sound issue. I found the explanation on the page below a bit confusing. I simply dragged and dropped the neck pickup onto the center pickup position. This puts the neck and center pickups together in one location. Then turn on the bridge and center pickups, adjust tone as you like, and upload to the guitar. Hope this helps anyone who's been fighting to get their "Sweet Home Alabama"/"Sultans Of Swing" sound accurate.
