1 kc_eddie_b 5 months ago I just saw a guy on-line selling his recently removed B70 from lower-end Gretsch because he had replaced it with a V-style B6. Now I'm seeing these new Penguins are equipped with a B7 format Bigsby as well. Is there something different about the neck sets on these newer Gretsch guitars that suddenly require the added string tension that the B7 delivers? Or is this trend just an effort to create some visual diversity within the Gretsch model line? I guess I don't mind the aesthetics of it, but as a purist it's hard not to want to see a B3 on a Jet-style Gretsch.
