Etymology: "Jazzer" is about as plain as English word-building gets: the noun "jazz" with the agentive suffix "-er," the same ending that gives us "baker" or "singer" for someone who does a thing. Once "jazz" became the name of a musical style, a musician who played it naturally became a "jazzer," and the formation follows the pattern of older trade and activity nouns. The suffix does most of the work here. Attaching "-er" to a noun for an activity yields a person who practises it, so a jazzer is, in effect, one who jazzes. The word's meaning therefore depends on "jazz" itself, and any surprises in its history belong to that base word rather than to this derivative.
