Reply to Question About Exchanging My S4

I recently bought my s4 at guitarcenter 6 days ago and I noticed that one of the filter knobs is pretty loose when I rotate it compared to all the other knobs which are tough and tight.

I'm wondering if it's possible for me to exchange my s4 for a new one since it's within the 14 day return period?

If anyone had any experiences with this, please let me know!

Thanks for reading!
