I had the chance today to A/B my D-50 with a 1997 Madagascar RW D-28 at our monthly folk jam. No contest, D-50 blew it away. Both could have used a string change, I know mine does. The D-28 did have lighter strings, .011s, mine has either .012s or .013s. Still, I think the D-50 was better playing and sounding.
