Other then a few edits for time, this is pretty raw and hopefully helpful. It is by no means totally comprehensive, so if there are chapters you'd like me to go deeper into, please let me know!
I would highly recommend JDR Assasin harmonicas for out of the box overblows. That being said, many harmonicas will work out of the box or with a tiny bit of TLC. Personally, I prefer to play Lee Oskar harmonicas for most of what I am doing and find that I can tweak those and use alternate tunings. The Trochulis/Game Changer harmonica is a great alternative to overbends if you are ok with using a slide. Hohner has a great reputation for making custom harmonicas that will overbend, but I have found harps by Suzuki and Seydel to work too. I have been very impressed by Bushman and JDR for the quality of the instruments, great pricing, and ease of set up to overbend.
