I'm an Amazon "Top 1000" reviewer and I'm known for no-punches-pulled reviews, not for raving about the products I've evaluated. But when I put these strings on my Eastman 810-CE archtop, I was blown away. When played acoustically the upper registers were bright and clear, and the lower registers had an old-fashioned kind of "snap" that I've missed with hex-core strings. I have been a big fan of Philippe Bosset strings, which are top-notch, but this set of Curt Mangan strings surpass even that lofty standard. I'm going to order another half dozen sets for sure. These are easily the best strings ever for my archtop.
very cool strings - just got a fresh set up on my Martin HD28VS and had them throw these on. Rich subtleties These round core's vibrate in a different way. Feels like 1974 on the porch! Very pleased Curt Mangan!
