[CAUT] Stuart & Son on NPR

[Ed Sutton]

About the titanium, I understand that it has very high impedance, it is very 
stiff. Sauter uses it for bridge pins, front and back duplex bars, as a 
plate upon which the duplex bars rest, and perhaps also for the hitch pins.

In any case, the result is almost mysterious. In the top capo section, the 
fundamental is very clear, all the way to note 88. Very, very nice.
