She had the pickups replaced.

What's also surprising in the budget theme of the discussion, is that she doesn't have effects either, just a tuner. And in the video she says she uses it because it anchors her cable near the mic.
I saw a local blues trio the other month, and the bassist absolutely nailed it.
He was also using the SX jazz, also just the tuner and he didn't know about her. So in a week I found two people using exact same setups independent of one another.
He was even just using the house amp, so none of that "This is my unique tone" kind of thing.
Those SX guitars are bloody good. I just got a 5 string Warwick-alike the other day and it's probably £200 too cheap for how it plays.
