How to mic the ukulele
Guidelines for miking the ukulele.

As is the case with all acoustic instruments, recording a ukulele is always a compromise between getting the full timbre of the instrument and isolation from other instruments or unwanted reverberation.
Omnidirectional mics for ukulele
If there are good acoustics and no other disturbing sound sources, a precise and highly detailed omni mic is ideal.
The 4041-SP Large Diaphragm or 4006 Omnidirectional Microphone are good solutions that will ensure that you do not lose any vital information. Try aiming the mic at the sweet spot, which will give a good blend of strings and fingers.
For a miniature solution, the 4060 CORE+ Series Instrument Microphone offers a wide variety of placement possibilities, and many live situations could benefit from close miking.
Cardioid mics for ukulele
If more isolation is needed, one or two cardioids or wide cardioids is a good solution. The 2012 Compact Cardioid is one good solution. Otherwise, two 4011 Cardioid Mics mics can be placed in XY configuration at the sweet spot using MMP-ES Modular Active Cable. The CXO4000 Compact XY/ORTF Stereo Holder can be used for this configuration.
For an A/B configuration, two 2015 Wide Cardioid Mics make a good solution.
The miniature supercardioid 4099 CORE+ Instrument Microphone is the perfect choice for all live applications. It offers lots of gain before feedback while retaining the clear and transparent DPA signature sound.
