So to clarify the California range, essentially all the ‘expensive’ range is all done in Germany. Some woods may come outside the country, eg if they use Canadian Hard Rock maple, other exotic woods etc. BUT it is all cut, glued, shaped, plekd, painted, finished etc in Germany. The tuning keys I think are made in another country, the Sandberg pick ups are not wound in the factory, but they are designed but Sandberg to their specs and made elsewhere.
The Electra range is manufactured in the Far East, BUT the parts are shipped back to Germany and all assembly and testing is done in Germany and final QC in the same factory as everything else, hence the lower cost.
To intensive purposes it’s all pretty much Germany and in house before it goes out to market.
Hope that helps - and they are fantastic basses
