Extension -- Effect?

[Arnold Schnitzer]

In my opinion a well-made extension gives the truest rendition of the lowest notes. That's because the extended E string has a speaking length of 51-53 inches. It is well established that the double bass is actually too small for its deep register, and it's also well-established that longer strings are better at producing low notes (hence the awesome bass strings on a concert grand piano). I'm speaking about tone and timbre here, not ease of play.
