I will start by observing that there exists, in SE Asia, the ability to manufacture musical instruments to a very high quality. I am not at all espousing a "quality can only be found from American manufacturing" point of view.
There is a whole 'business' point of view that should be considered. The original vision of The Heritage guitars was pretty clear. Working instruments for working musicians, patterned after the much-loved originals, built in (what was left of) the original factory, under the guidance of some folks who were involved in the creation, build and sale of those much-loved originals. With the departure of the OG owners/founders of The Heritage, corporate interests have taken the helm. Corporate interests being what they are, profitability and growth become the core of, if not the whole "uber alles" mantra. Having personally espoused, for many years, that 'the only things in nature that experience non-stop growth are kudzu, bamboo and cancer,' I will refrain from expounding further on my thoughts thereof. Suffice to say, I think the current management has a different set of goals than the OG owners/founders did, and their marketing--which translates over to their production choices--reflects that. Nothing wrong with it, it's all just board room decisions and calculated risks.
If it were a perfect reality, the OG owners/founders would have continued forever. They would have learned a couple things along the way, like maybe 'pay a little more attention to QC,' and The Heritage would exist in a perpetual Golden Age. But, we don't live in a perfect reality. Otherwise, I'd be typing this from a 60' Viking enclosed bridge anchored off the coast of some uninhabited atoll in the Caribbean. Instead, here I am in the vast wastelands of Michiganistan, questioning my life's decisions.
The current stewards of the brand can make whatever decisions they like, and I wish them the best of luck. I'll stick to, ah, pre-loved Heritage guitars.
