Why is my bridge lifted?

Hmmmm, did you tie it too much?

@Tink1113 no, I tuned it to standard and that happened

You need to reseat the bridge.

loosen the strings and research your brand and model to see if it is a repair you can do. If not take it to a reputable repair shop.

@Dog it’s an electric with a whammy bar, not an acoustic

Are they different strings?

@loser yes, light gauge

Your guitar is not set up for light gauge strings.

In order to tune light gauge strings they require more tension.

You will need to either adjust the bridge setup for light gauge ( best done at repair shop) or go back to the prior gauge strings.

@chupacabra I don’t think that’s it because I’ve done this before with light gauge strings as well
