I would like to know what brand Jerry plays on most of the lessons

I play either the Hohner Marine Band DeLuxe or the Hohner Crossover.

When Jerry plays he gets a great rasping sound, or almost a rattle, out of the harp. Is it the harp, or something else that he is doing? It's a great sound.

Most often it comes from making a guttural sound from the back of the throat as you attack the note.
