Bottlehead phono preamp project during Coronavirus boredom?

I recently received word from the school district that I work for, that I would be home providing online education to my students. So I plan to have plenty of "home time" in my future and was thinking of building a kit. My question to all Audiogoners is:
Is building a new Bottlehead Reduction 1.1 phono preamp a worthwhile project? What is the quality of sound? Is it only for MM cartridges or will low output MC cartridges work?

Thanks Gentlemen!
