What customers say
This foam kit for the GMMK Pro is overwhelmingly praised for delivering a dramatic acoustic upgrade. Users report that the modification effectively neutralizes the stock keyboard's metallic resonance and hollowness. The primary benefit is achieving a deeper, more satisfying sound profile, elevating the board to rival higher-end customs. Reviewers consistently highlight the high quality and precision of the material and cuts, ensuring straightforward, perfect fitment during installation. For its modest cost, this foam provides the single biggest sonic improvement, making it an essential, high-value modification strongly recommended by the community for superior sound dampening.
Know before you buy
The plate foam fills the empty space between the PCB and the plate, which helps dampen high-pitched metallic resonance and keyboard hollowness. This results in a deeper, more refined 'thock' sound profile.
The 3mm foam is the standard choice for most builds, offering a balanced sound profile. The 4mm option provides a denser fill, which further reduces acoustic vibration but may feel slightly firmer when typing.
The Flex Kit is designed for users who want to maintain the gasket-mounted flex of the GMMK Pro while still improving the acoustics. It is specifically engineered to provide sound dampening without restricting the natural movement of the plate.
Installation is straightforward, though it does require disassembling your keyboard. You simply place the foam layers between the plate and PCB during the assembly process; no permanent modifications to your board are required.
Yes, StupidFish Designs offers specific cuts for both ANSI and ISO layouts. Ensure you select the correct version for your specific keyboard configuration to guarantee a perfect fit.
