My guess is that they will discontinue everything they possibly can that doesn't have the max possible sales. In fact, I would suggest that they don't care a hoot about sales, they want return on investment.
They have only so much money to buy product with, no matter what. The only way they can keep going is to maximize the ROI, and that does not mean sales per dollar invested, it means dollar profits per dollar invested.
Evidently their dollar profit return per month is not as good as desired for the 2 PRO. Most of the Ampeg stuff has never sold tons, espensive stuff usually does not, but for SLM it was profitable, and still amounted to a good cash flow.
Since GC is actively pushing the Loud brands out of their stores, bit by bit, I suspect their sales of Ampeg are not what they were.... And with GC probably demanding better and better margins, as per Walmart, they don't get the profits they need.
