Le Fay is a German boutique bass guitar maker based in Kiebitzreihe, a small town in northern Germany. Founded in 1985 and run by luthiers Reiner Dobbratz and Meik, the company handcrafts 4-, 5-, and 6-string electric basses — including fretted, fretless, headless, and multiscale configurations — with components such as pickups, saddles, and bridges developed and manufactured in-house.
