Kala just uploaded a nice little video showing you how they string a uBass with Pahoehoe strings at the factory. In it they emphasize the tricky maneuver they use to properly seat the G and D strings.
The string up part actually starts at 0:34 in the video. But the intro is pretty cool.
Watch the video Here.
It’s a nice companion video to Kala’s previous video featuring Mike Upton stringing a uBass.
Both videos use different methods (which achieve the same ends) for stringing the D and G strings. Both Mike’s and the factory’s methods are effective. Mike’s seems to me to be a bit easier to master–making a “lasso” instead of doing all the threading “calisthenics” the factory guys use.
Pick the method you like best.
