The Mammoth75

A premium isolation gasket mount 75% from Wuque Studio. Features a large, hot swap knob on the top right and a 4×4 artisan cluster just under it.

Mammoth75 is Available in 32 unique configurations. You can choose among 4 different anodized aluminum top cases, and 4 different aluminum and brass bottom cases. 

This is a limited edition of the Mammoth75. Mech.land has been assigned 9 units with Brass Mirror PVD bottom case and 12 units with Brass Sandblasted bottom case.

Highlights:

• Sandblasted Diamond Cut Mammoth Weight
• Hotswap knob
• Special Gasket Structure with Daughter board

  The plate PORON foam is the same size as the plate, and it will touch the entire bottom case to achieve a stable typefeel. There is an adhesive PORON sheet pre-installed under the PCB for a deeper, more pleasant sound.

• Two magnetic knobs in each kit.

  Each kit comes with an aluminum knurled knob with a CNC engraved pattern, and a plain brass knob with a radial brushed finish. Knobs have a magnetic base to make them much easier to swap out.

Acceptable Quality Standards:

Due to the nature of mirror-polish treatment, there may be minor, unavoidable dust points/micro scratches on the mirror finish of the bottom case. Small dust points/micro scratches that are only visible in just the right angle of lighting, small scratches inside the keyboard case, or dents on the case that are not visible when the keyboard is fully built. These are normal and within our quality acceptance. Check more details here.
