I bought the S-620 TB in blue and I’ve had it for a couple of weeks now. It looks awesome, the neck feels nice and the fretwork is great, I haven’t noticed any fret buzz. I’ve never had anything to do with a Floyd Rose before and this one seems a bit cheap, I had some problems screwing on the trem handle as the threads were not so smooth. It went on with some patience and back and forth with the nut. But given the price point for the guitar, that’s fine with me.
I am fairly new to the guitar, call it a COVID reinvention.....I played in my teens briefly and now I’m in my 50’s, so it’s for home use only. I think if you’re new to guitar and you want a nice piece of kit to play some of your favourite rock and metal tunes this is a great and economical way to go.
