After talking with Josh and Gary Upton yesterday in Boston about commissioning a carved 5-string Concord more or less along Karr lines (and getting the go ahead at home from the significant other for a new bass), I am putting my Deluxe Karr Hybrid on the market.
This is the exact bass in the video: https://www.youtube.com/watch?v=SG1KtGZOxSY
It is in pristine condition and sounds much richer now than when it first arrived 4 years ago. I've done everything from Mahler 1rst (solo) to loaning it out to visiting jazz bassists from Europe, and it has never let me down.
It's a terrific bass. Currently strung with Jargar mediums
$5500.00 firm. I can arrange to have it shipped at additional cost.
