Extra tension on G

I had my Axis set up a couple of months ago, and I immediately noticed there was some extra tension on the G. I had it set up with Paradigms, so I wrote it off initially as just a different feel for the different strings. Over the weekend, I swapped strings back to my regular Super Slinkys, and I still have the same issue. Everything else feels good, but when I hit the G, it seems extra tight. I can take it back to the tech, but given how long I’ve let it ride, I’m pretty sure that’s going to be more $$. Just thought I’d ask for suggestions here first.
