GK Fusion 550 Hybrid Power Button
 

The power button on my GK Fusion 550 Hybrid sticks and will not turn off. I can press it to turn it on, but the power button will not pop out when I push it again. I can hit the side of the amp a few times and it will eventually come out, but I don't want to do that.... Anyone had this issue with the GK Fusion line??

No I have not, first I have heard of this. Maybe try (with the power cord disconnected) some rubbing alcohol dampened on a rag and push in/wipe off the button. Maybe something sticky got on it?

Did this and it worked great, then went back about 10 minutes later, and it kept sticking.

Sounds like something got deep inside in the switch? If your still in warranty contact

My mute button did this.
GK replaced the switch, no probs.
