[Description]
There are two designs that mount Silicone differently :
White GL base have more room for the silicone to flex for smooth operation. Good for overall setups.
Black GL base have better stability, but it will slightly add more tension. Good for low tension setups.

Based on switch spacing, there are two options:
Fixed Spacing is traditional mounting method where all the switches have same distance/spacing. Good for user who prefer simplicity.
Variable Spacing, it allows tuner positioning the switch individually to adjust sensitivity for each directions. Good for user who like tuning lever. Switch Spacer needed to set the switch spacing, SOLD separately. Switch spacer set include 7pcs form 15 to 17 mm (0.5 increments) "+ tilting" and "- tilting". Popular switch spacing are 15.5mm, 16mm, and 16.5mm.
*All necessary screws are included on every GL base.
Fanta base has build from traditional Korean Fanta lever design.
Regarding Fanta base, fixed switch spacing with build in tabs guide, easier to install switches at determined spacing.

Always double check your spacing and actuator combination, make sure the actuation not bending the switch hinge/blade on full throw.
[Tips]
When adjusting the switches you don't need to unscrew completely, because the nut inside the base can be out of place and you will need to open the base to fix it. Just make 360 rotation counter clock to loose the screw until switches can move, then it is ready for adjustment.
When fixing the screw after adjustment never do overtight, it can damage the base and makes difficult to remove the screw, just put enough tension to keep the switch in place when actuate. Some tips, tighten it using thumb and pointing finger only when holding screwdriver to reduce overtighten risk.
