I don't want to beat a dead horse here, but I'm going to encapsulate my take on this issue in this post and hopefully leave it here, from this point forward.
In terms of Ampeg: It's not a matter of patriotism, per se.
But it IS a matter of good jobs leaving just for the sake of the bottom line, coupled with the gear quality not necessarily improving (haven't played the imported heads, but wasn't into the cosmetics on a cab I used recently from China or Vietnam), along with a price advantage not necessarily being passed down to the consumer. Also, just a sense of an iconic brand somehow being watered down. I couldn't be the only one to feel this way. Lastly, all of the people I've been working with at the company for years are no longer there; those are people with which I had built great relationships.
That is my rationale for not continuing an official endorsement of the products.
This doesn't mean I won't use the gear. I LOVE my U.S. Ampeg gear. It sounds great, it works great, it looks cool. It's possible that nothing will sound like my sealed 810AV cabs, for instance. Or my B-15R. They are singularly awesome. I use them all to this day.
But those changes in their business model which I touched on above have made it so that I don't have interest in ENDORSING the product any longer. I haven't been convinced to do anything otherwise by the company or anyone else.
As far as an allegiance with another brand, I may or may not decide to go down that road, depending on my future needs. Regardless, wherever I end up, the relationship would have to be based on some sound fundamental principles and candid agreements for the good of both sides.
Hopefully that all makes sense.
Best,
JMJ
