James Ham is a legend in the double bass luthier world.  After a multifaceted background that landed him in Victoria, British Columbia, James Ham created a series of revolutionary designs for the double bass.    His first instrument was commissioned by Gary Karr after a deep analysis of the various positive and not-so-positive traits of the Karr-Koussevitzky bass, Jim created a marvelous instrument on which Gary Karr still plays.  In fact, Gary will only perform somewhere these days if there’s a Jim Ham bass waiting for him!  Here’s a photo of me with Gary and his lovely Jim Ham bass.   We dig into Jim’s adjustable and removable neck system, which eliminates the need for bridge adjusters.  We also talk about Jim’s founding of the Violin Society of America Double Bass Workshop at Oberlin.  We even dig into our shared South Dakota roots!   This is a great chat with a luthier that has had a big impact on the lives of many bass players.  Enjoy!   Listen to Contrabass Conversations with our free app for iOS, Android, and Kindle!
