Here's a brief except from Bruce Petros' page in his own words:
Basically this is virgin redwood used in Tunnel 13 built in 1880. This was the location of the Last Great American Train Robbery in 1926. When it caved in in 2003, Petros guitars acquired a bunch of the best wood and turned it into guitar sets. It is the glassiest, stiffest tone wood we have ever used and makes an exceptional instrument.
