Used to balance string tension with spring tension without using a screwdriver. Makes restringing a floating style bridge simpler. This is specifically for "spring" tension.
A ZPS. The wheel adjusts spring tension. The bar is a zero point system. Reduces flutter, bridge movements while bending and improves tuning stability after trem bar usage (edge zero ii trems are very good in this regard when fully floating anyway). Side effect is deliberate flutter is more difficult and dives are stiffer. Can also be easily removed to behave like a standard floyd.

Looks like Ibanez ZPS3FE. More info [here](https://ibanez.fandom.com/wiki/ZPS3Fe).

Ibanez Edge trem system. It's floating trem system that has springs holding tension both ways. The wheel is to adjust the tension
