The Jazz drum kit is very different to the rock kit. Many Classic Jazz producers will not allow close up miking of the kick drum. The timing in jazz often winds up on a different section of the kit. For instance, ride cymbals or hi-hat can be keeping the time, while the kick and snare are only used for accents. There is also only one rack tom and a single floor tom. This opens up a window to be truly creative. Great jazz drummers rarely overplay. This allows a greater scope for mic technique, mostly due to the reduced sound pressure level that jazz requires. Gating and super isolation become enemies to most jazz producers.
