As the owner of a Player Strat and having played the Jaguar and Telecaster in the same range, I thought I knew what to expect from another Mexican Fender.
I was wrong.
The Mustang 90 feels cheaper than all the others from the range. Not just because it's smaller and lighter, but in terms of overall quality. The fret ends were sharp, saddles in bad shape, knobs sticking, fretboard dry as a bone. It didn't feel any better than the Squier Bullet, just a bit heavier.
If you are willing to spend the cash on a set up after you get it, you do get a fantastic sound from the p90 pickups. Warm, sweet tones that can turn into a noise machine with some gain. With a bit of fuzz this sounds like a beehive but... Good. Hard to explain, it's an indie rock sound that I really liked.
The lack of a belly cut was frustrating for me, as the guitar sits at an odd angle while standing. Might not bother everyone but I appreciate the comfort of a strat.
Sadly the issues with quality, plus a defective nut led me to return it, and I won't be getting another, I'd prefer to put p90s in a better quality guitar. It's just not good enough in the price range to get so many issues and for it to feel so much worse than the rest of the player series.
