I own several Gibson guitars (Vintage). 1) 1959 Les Paul "Honeyburst"; 2) 1960 Les Paul Special; 3) 1965 335; 4) 1965 J-45; 4) 1952 L-7CN
Among those and several other collectible guitars, the L-7CN is my favorite guitar to play. It is strung with flat-wounds. Butter.
Thanks for the interesting thread.
