JoLida split, and has the good distributor in NJ, and the less than good distributor from China. They are somewhat like Rogue, where they do have some good stuff, and then some dogs.
There are different manufacturers who have had great success utilizing parts or wholey manufactured lines from China, but they utilized American QC and QA managers. Monarchy Audio and Eastern Electric are examples from the past that succeeded in properly sourced production.
In the long run, generally you do get what you paid for...if you are going to mod, then why not source and mod on vintage or American gear of proven track record?
