All you really need are two harmonicas in the key of C and A, but if you only have a C that's fine too. If you want, you can bring multiple key harmonicas. For the sake of the instruction portion and jamming, we'll stick to C and A harmonicas. For the die-hard learners, we encourage you to bring a recorder and/or a pad of paper, and pen to take some notes down. Any and all recordings both audio and video, must pass Adam and Ronnie's approval before posting or sharing anywhere.
Lastly, be sure to bring cash in order to purchase product such as CD's and other learning material; as well as food purchases (lunch may be cash only). For those who would rather purchase merchandise with a credit card, that will be possible for Ronnie.
