Hi TB, I recently acquired a Kala Journeyman U-Bass. It came with the Kala Roundwounds. I also got a set of Aquila strings, the Thunderblack ones. When I tried to install those rubber noodles, I learned that the holes in the body are not wide enough to fit them. I've seen people play that Journeyman U-Bass with the rubber strings and the Aquila website only lists one gauge for the black and white strings. The red ones are a bit thinner, but the red E string is as thick as the black A string and the black A string also won't fit into the hole of the E string. Has anyone here encountered the same problem? Is there an easy fix? Maybe drill the holes larger? Maybe filing them?
