I would also contend that likely the reason Ampeg can get away with selling them is because the folks that buy them do so because they can't afford something more expensive and feel the Ampeg name will bring them some credibility and respect among their peers. I've played for enough years to know there is an underlying school of thought that owning a particular brand brings the owner a certain amount of respect.
The guy I bought mine from bought it new for that very reason. He calls me up and says "I bought an... AMPEG, dude!" He really thought he was going to make himself appear as a serious musician by rolling in with an entry level Ampeg combo. And this was to be his gigging amp! He quickly learned that a brand name isn't everything.
LOL! For the same coin, he could have bought a used Hartke 3500 head and a 4x10 Transporter cab...
