Gazzew Boba U4T Tactile Switches
Housing Material
These housings are Gazzew's New proprietary plastic blend that is softer and smoother than nylon, resulting in an excellent thocky sound profile. It also fixes the yellowing issue when exposed to certain foams.
Spring Info & Factory Lubing
The stock springs are a mid weight 65g Korean spring, so there is no need to swap for quality/tolerance reasons.
Boba tactiles also feature a redesigned leaf made specifically for tactiles - allowing for that sweet sweet bump and virtually no leaf ping. The springs are donut-dipped in lube to prevent ping, and the leaves are lightly lubed - the sliders are completely dry.
Lubing Recommendation
For brush lubing, I suggest a light lubricant like TriboSys 3203. Coat the stem (but not the tactile legs or silencing pad) with a light coat.
For those interested in trying the Gazzew Method, pick up some Loob-3G in a dropper bottle.
