A '74 vs a '78, both are the same woods except a rosewood vs ebony bridge, yet they sound different. The D-55 does have XL 13s on it and the D-50 has Veritas 12s, but even when they both had Veritas 12s the D-55 was brighter. The D-50 isn't nearly as bright but is extremely well balanced.
What's your favorite? I can't even decide.
