Looks like a nice bass 
Looks comfortable to play. Funny though, made in Korea, but called "US Masters." I wonder what they are implying?

Thanks. It's pretty lightweight, really well balanced and has a great tone.
I had wondered the same thing about the origin of the guitar and researched it pretty extensively.
US Masters was a small guitar manufacturer based in Wisconsin. They made a line of semi custom guitars there (i.e. made in the USA true to their name), but somewhere in 2008/2009, they started an affordable import range with the EPiN and EPiB models, calling then the US Masters Design range. These imports were initially made in Korea and around 2013 onwards, they moved the manufacturing lines to China. They did continue to build US Masters guitars and basses in Wisconsin alongside the imports in their custom shop.
The company eventually went under and the business was sold in 2015 or thereabouts... don't know what happened after that. Their used guitars and basses have a good reputation for quality but don't do well in the used market.
Interestingly enough, there's a delusional chap on Reverb that has the same exact bass listed for $2000 more than what I paid for it.
