I am a big Gretsch fan and did enjoy the tone comparisons they did with the pickups and guitars. The issue I had was that they got so many facts wrong. They did thankfully say several times "I'm not an expert don't quote me on that", but in an episode specifically tailored to teaching people about what a specific brand can do and their history.... maybe actually do a little research and have the facts before you record? They do this a lot. They have the enthusiasm, but obviously not the time to do these deep dives so they don't really relay much information. It all just ends up being filler with a few interesting nuggets buried in the hour long episodes.
