Per request, here is some audio of the most recent parlor guitar.
Also, big thanks to Steve Cheseborough, a great blues player and owner of a Sipe parlor guitar, who did the playing. A link to his music is here. The audio sample is a 16 bit / 44.1 khz file recorded on a tascam DR-05 portable recorder at about a distance of 4' with no post processing or effects -just straight from his hands to your ears.
