Hi all, and Damon the Xr sound a hell better then the Xv3080, especially the drums and bass and the guitar sounds. The piano's sounds have also been improoved. The great thing about this unit is that you can expand your sample memory to 512 megs of ram. As far as the hamond organ sounds, I believe there some pretty close sounding hamonds on this baby. Further nore you could purchase Cd's which has dedicated 60's organ sounds.
