LS “Lucky Strike” Log explaination in the words of luthier, Lance Krangenbrink:

Craig Carter’s now famous log. Craig located this log in north-facing freeway easement through a redwood forest. He estimated it had been down about 30 years. It fell downhill across a small dip, suspending a good portion of the log in the air; thus it cured in ideal conditions. The portion salvageable was about 3 feet in diameter, 60 feet long. (Unfortunately, much of the best part of the log was lost to fence-post hunters.) Craig began to harvest it in Fall 1993; final harvesting was completed by Alicia Carter and neighbors in Spring 1997. Some soundboards were cut by Craig as early as Spring 1994. Soundboards from this log have been made into fine steel string (including arch top) and classical guitars. Smaller billets have produced mandolins, as well. Stiffness to weight ratio is said to be excellent; grain pattern and coloration generally even, very straight, with lots of “silk.” Sound characteristics combine the warmth of cedar with the clarity and color of spruce with an added "sparkle". This log set very high standards for redwood soundboards – ones almost impossible to match. Craig cut into over 100 downed logs before he found one – the LS -- that met his exacting standards. He was a classical guitar player and planned to use this wood for his own classical guitar building.
