You can probably add in quite a few things they aren't real good at too. One would surely be the cheesy videos Dave McClaren likes to make starring himself sitting in Leo's Lab "left just the way it was the day he died" he likes to remind us. Then *** are you doing in their Dave? That's sacred ground.
And here's another example. IMHO the demo video from Premier Guitar of John Bohlinger doing a demo of the Tribute Doheny is 1000x better than any that G&L has ever produced themselves including some of the G&L Jams they produce. And as much as I respect Steve Araujo IMHO Ed Friedland G&L bass demos are more instructive.
