Hello Tomo,
I wanted to suggest a topic for a lesson which actually might be more appropriate for Tomofujitamusic: The Fender Tone Master line of Fender amplifiers which came out a few years ago. I imagine that a lot of guitar players would be interested in your unbiased opinion (as always) on for example the Tone Master Deluxe Reverb which was the first to be released and has gone through a couple of iterations already.
Best Regards,
Jerome Oks
