The MEINL Pure Alloy Custom medium-thin hi-hat cymbals feature a thin top and medium-thin bottom, giving them the dynamic range needed to be crisp and sensitive in the studio as well as full and loud on the stage. They’re geared toward professionals and advanced students looking for bright sound without excessive overtones.

MEINL produced the Pure Alloy Custom line in response to their players, who requested thinner models from the Pure Alloy line. The result is this line of medium-thin cymbals, made from the same B12 "Pure Alloy" bronze as the rest of the line. The alloy places these cymbals between the super-bright B8 bronze and dark B20 bronze, with the lighter weight pushing Pure Alloy Custom cymbals slightly darker on the spectrum than the regular line. The thin weight also makes the attack slightly softer, with a warmer body and faster decay. MEINL was careful to preserve the bright shimmer this series is known for, but retooled it for a new type of player. And to make the line stand out, they also applied a new "smoked bronze" finish to the top and polished the bottom to a brilliant finish.
