In all aspects my Fender Mexican Strat (with MIDI pickup which I don't use) sounds better. However, at the ST-62 SB's price, it may still be a good option.
The ST-62 looks good and the frets are filed down well so you won't cut your fingers like many budget guitars. However, setup was disappointing. Action was set way too low causing the top bass string to sound awful. After adjusting the truss rod to raise the strings, the bass string sounded better but still not that good. I prefer a real Strat's bass string to sound a bit more like a Fender Precision Bass sound which is what I get from my stock Mexican Strat.
If you are a shredder or prefer highly overdriven sounds, the ST-62 is a good choice. For clean sounds, however, while the bottom 3 treble stings sound good, the other strings get progressively worse as frequency goes down. The 3rd string is just slightly worse. The 2nd string worse than the 3rd and the top bass string is kind of cheap sounding even after action was adjusted.
Problem: HUM
When I moved around to various locations near my pedalboard, my Mexican Strat was basically hum-free in all pickup selector positions. In contrast, the ST-62 hummed like crazy in any pickup selector position. The ST-62 had to be angled and positioned carefully when playing to eliminate most of the hum.
I will probably replace the neck pickup with something better and see if that helps. Because of the hum problem, I wouldn't try to play this guitar in a live venue.
