Exciting to build and a nice challenge ...

Exciting to build and a nice challenge to calibrate for highest output and lowest distortion.
Fantastic quality all the way through, don't think I'd be happier with an original... just poorer...

M87

SUPER

Great

Really happy with our stereo pair of the m87 mics. Can't personally compare it to the original vintage U87 as I've never used one but this build was easy enough for us to do with a few months of experience building guitar pedals. Happy with the sound and the materials are very solid and well made. Also like the box. Would definitely buy another kit or two from Mic and Mod
