The kick or bass drum is easy to record since it is usually played (in pop music) at the same volume throughout the song. Producers and engineers look for a "marriage" of the bass drum with the bass instrument because they both occupy and make up the important bottom end of the record. Fig. 3 shows my usual starting place for the bass drum mic. The Beta 52 in the picture is placed half in and half out of the hole in the front head. This distance is variable and I try to keep the mic pointed exactly at the spot on the rear head where the beater hits. Fig. 4 shows an old '70s' trick where the microphone goes right inside the drum. This produces a very present and dry sound that was great for disco music before the Linn drum machine. You should put a weight (sand bags are good) to hold the mic in place inside the drum.
