Unlike most people that have posted above, I have seen the quality issues on my own Heritages, and I've heard about many quality control issues wih pre bandlab Heritages. One of my good friends was a dealer for Heitage. and he told me some stories about how many bad ones came through his store. And of my 3 H150s that I own(ed), two of them had nut and fret issues that had to be addressed before I could get the action down low enough to where I like it. And I had to sand out more than a few file marks. When I see the term "Golden Age" referring to pre bandlab Heritages, I just roll my eyes.
For the people that got good pre band lab ones, that's great, but for those us who have had to deal with the issues on the older ones, it was a pain. I originally got into Heritages, because I'm a serial modder with pretty good guitar repair skills, and I figured they were so cheap at the time, if I had to do a little work on one, it was worth it. And I really liked the wood on them, they sourced some nice Honduran mahogany, Eastern flamed maple, and Indian Rosewood. And if you were patient, you could find a good one with a decent low weight. But those low prices are history now, so if I was to buy an older Heritage, I would demand a return window.
That said, the H150s I have now are good to go, and with the way I modded them, they are great guitars. And he H535 P90 that Kuz sold me was set up really great, and I knew it would be a good guitar, because it was Kuz, who's a straight shooter, and he would never sell me a guitar that was sub par.
