Though I've no experience with the Rondo brand as such, they appear to be one of a growing number of budget instrument makers. And, largely, these budget instruments are very good for the price. Indeed, some might say they are very good despite the price!!
Before buying the used Harper fretless 6 I did some research. It seems there are one or two Far Eastern factories making guitar bodies, necks, etc to a very high standard, and it is these bodied and necks that get built then badged. One factory, I discovered, makes theses components for over 400 different brand names ... including the big boys for their lower priced models: as I remember, Fender and Ibanez were named amongst them. Another manufacturer is Cort. Though they make for that brand, their business is aimed at making bodies and necks for other's to badge as their own.
The manufacturing machinery at a given factory is surely set up to make the highest quality possible? It seems ludicrous that they make low quality gear for one badge then high quality for another.
I'm sure players of all levels will benefit from these budget priced but non-budget quality instruments.
Just a thought.
