A preamp for the stereo clippy EM272 mics made by micbooster in the UK. These are the same capsules used in the LOM Uši Pro so should work just the same for those mics, but I haven't tested with those. Provides plug in power and has mono/stereo inputs and outputs.
Based on this reference design and this thread on the lines forum.
Here is a short recording of a cheap ukulele through the preamp.
