MEK is a small German boutique electronics operation specializing in guitar effect pedals and DIY build kits. The brand is associated with the German shop uk-electronic.de, based in Krähenberg, Germany, which carries MEK-branded finished pedals alongside a large catalog of build-it-yourself circuit kits and PCBs.

MEK is best known among pedal hobbyists for its Tubedrive series — the TD-1, a TS-808-style Tube Screamer interpretation, and the TD-2, a more flexible overdrive with an internal dip-switch that selects between Tubescreamer, Fulltone-style, and a house TD-2 voicing, plus a toggle for boost, hard, and soft clipping modes. The pedals use true-bypass switching and can be powered by 9V battery or a 9–18V DC supply.

Beyond the finished Tubedrive line, MEK's output is heavily oriented toward the hand-built and DIY community, with kits covering ground such as a Hotcake-style overdrive, a Dynacomp-style compressor, a Zendrive-style clone, a BSIAB2 ("Brown Sound in a Box") distortion, a Dr. Boogie high-gain circuit, a PT-80 digital delay, the D'verb digital reverb, and a tap-tempo tremolo, along with bare PCBs for classics like the Big Muff and Fuzz Face. The brand has a low profile outside of European boutique-pedal circles and is traded mostly through marketplaces like Reverb.

MEK has 6 products cataloged on Equipboard, including Overdrive Effects Pedals, Boost Effects Pedals, and Fuzz Effects Pedals.
