Hammond organ and Leslie speaker
The Hammond is an electromechanical organ: until 1975 a spinning metal tonewheel near an electromagnetic pickup made the signal, which went to a speaker cabinet, and drawbars set the mix of harmonics. The Leslie speaker is the usual cabinet. Models: 2 x 61-note manuals and 25-note pedals (console), or 2 x 44-note manuals and 13-note pedals (spinet). The organ makes no sound by itself; the mic goes on the Leslie, so the Leslie is the source.1

2 - Distant Royer R-122mono, 5.5 ft from the cabinet
Example 3: a Royer 122 ribbon 5.5 ft away; "really close to what the Leslie sounded like in the room."

2 - Close 2 × AKG C 480Leslie top rotor, 180 degrees, 9 in away (pair)
"A number of engineers prefer the sound of small-diaphragm mics for the top rotor": AKG C 480s at 180 degrees, 9 in.
2 - Close Sennheiser MD 421Leslie bottom, 10 in; or top rotor 6 in (Lynn Fuston)

"A time-honored Leslie miking method includes using a pair of Neumann U 67 mics about 5 feet in front of the cabinet and 10 feet apart."
2 - Close Neumann U 67 / U 87 or ribbonsLeslie bottom rotor
"Some folks prefer to use condensers like Neumann U 67 or U 87 on the bottom rotor instead of dynamic mics, and others like ribbons."
2 - Multi-mic plan Sennheiser MD 421Leslie, four-mic setup with a Neumann U 47 FET on the low end (x2)
Ben Fowler: "Sennheiser 421s with a FET 47 to perfectly balance the lower frequencies of the B3" (summary text of a video; four mics).
3 - Close Neumann U 47 FETLeslie low end
Combines Sennheiser 421s with a FET 47 for balanced low frequencies (Ben Fowler, Blackbird).

Listed under "Leslie Speaker" in the Shure Microphone Selection Guide (no argument given).
4 - Multi-mic plan top rotor: Shure SM58 (pair) + KSM44 + bottom: Shure KSM44top rotor and bottom
"I would put something like a '57 or '58 mic on the left side and the right side close to the rotating horn about an inch or two away."
5 - Multi-mic plan top rotor: 2 × Shure Beta 56A + bottom: Shure KSM27top rotor (outside the wood) and bottom
"I used 56s on Babyface. I mic on the outside of the wood because it gives the widest stereo response."
5 - Close 2 × Shure Beta 57ALeslie horns, loud or cramped stage (gospel/rock) (pair)
On a loud stage a pair of Beta 57s works very well: good mid and high reproduction, "excellent off-axis rejection".
5 - Clip-on Shure Beta 98Leslie horns, clamped on the cabinet, 90 degrees to the horn axis
Wilco FOH engineer likes Beta 98s for the Leslie high mics; one capsule outside, one far inside the cabinet.
5 - Close Shure KSM137 / KSM141 / SM81Leslie horns, quiet jazz stage
Jazz: a pair of SM81s or another cardioid condenser (KSM137 or KSM141) on the vents or open back, but not too close.

5 - Close Shure SM57Leslie top rotor (horn), 1 in from louvres or 12 in away
"The standard miking approach is a single mic in front of the bass rotor and a pair for the treble horns, and usually dynamic mics are used, such as Shure SM57s or Sennheiser MD421s."
6 - Close Sennheiser MD 421Leslie top and/or bottom
"Usually dynamic mics are used, such as Shure SM57s or Sennheiser MD421s." (Paul White)

Where the sound goes
The classic cabinet has three parts: the bass speaker fires down into a rotating drum with an angled baffle, the treble driver feeds a rotating horn at the top. The crossover is at about 800 Hz. The horns and drum turn in opposite directions with slow ("chorale") and fast ("tremolo") speeds. The model 122 has one 15 in woofer and one compression driver with horn; the horn is double, with one side blocked for balance. There are several variants (single rotor, extra reverb channel).6,7
Recording it
- Standard: one mic at the bass rotor and a pair for the treble horns, usually dynamics such as SM57 or MD 421 (Paul White, SOS).
- Recording Magazine tested eight setups on one cabinet. Examples: AEA R84 ribbons about 14 in from the cabinet corners at about 90 degrees on the top rotor, with an RE20 at 10 in on the low rotor; a Royer 122 at 5.5 ft in mono, "really close to what the Leslie sounded like in the room"; a KSM44 at 2 ft; AKG C 480 small-diaphragm mics at 9 in on the top with an MD 421 at 10 in on the bottom. Lynn Fuston uses an MD 421 6 in from the top rotor with a KM 84 on the bottom. The classic distant method is a pair of U 67 about 5 ft in front, 10 ft apart.
- Ben Fowler (Blackbird) uses four mics, combining Sennheiser 421s with a Neumann FET 47 for the low end, according to a video summary.6,2,3
On stage
Shure gives advice by stage: a loud, cramped stage (gospel, rock) calls for a pair of dynamic cardioids or supercardioids (SM57, Beta 57, Beta 56) close to the louvres; a quiet jazz stage allows a pair of SM81, KSM137 or KSM141 on the vents or open back; for the low rotor a kick drum mic (Beta 52A) at the baffle a touch off axis, or a KSM44 or KSM27. Beta 98 clip-on mics are used on the horns.5
Problems to watch
Wind noise from the spinning horns and drum when close-miked (use windscreens or move off the airstream); a loud relay click when the speed changes, so put the bass mic on the far side of the cabinet; phase between a spaced pair; condensers picking up other stage sound.6,2,5
