Well, I watched this because I was thinking about getting an Instek Audio Generator. Happily, you like it. However, you bounced around so much through this video talking about your scope, THD meter, and other things I had a hard time concentrating on the video. I can tell you are knowledgable about electronics and equipment but you might want to rehearse your videos a little and try and keep from going off on too many tangents. I am not bashing you or the video I am simply trying to help you publish better videos. I wouldn't even call my comment constructive criticism as I hate doing that. I simply see so many RU-vid videos and thought you might work on yours a little. I hope this comment does not anger you.
