It's not surprising to me at all. There isn't a whole ton of difference between "cheap" and "upgrade" guitar electronics these days.Nice! That's a good plan to make it your own.
It continues to be fascinating to me that many of us have found the pickups and electronics quite adequate so far. Good strings seem to be the only constant on necessary upgrades.
I'm playing mine 3x per month with our church band and it just keeps growing on me.
Happy it's working for you too!

For the most part, as long as it doesn't fall apart on you, and you know how to operate an amp well, you don't really need to "upgrade" much, electronically. Most electronics these days are garbage. Not a ton of real-world difference between stock Squier electronic components and what most people would "upgrade" to. Usually, people would be better off learning how to operate an e.q., rather than replacing stock components.
