HMX
Hmx X Bckeys Martini V2







The HMX Martini V2 is the rail bottom-out version of the Martini switch, and the first HMX RBO switch pairing an LY stem with a PA-2 bottom housing, the combination used on HMX Cheese. It does not sound as clacky as Cheese, because the rail bottoming-out stem drastically changes the sound profile despite identical materials. Lubed by the Snow Crash method: only leaves and springs, thin mixed 205g0 and 105g0 on leaves and dry film on springs, with stem and housings left dry.
