Re: S570MQM or RG3XXV?
So I have owned a Korean S470 in the past, and played the RG3XXV in store. In my experience with the RG (and everyone else that has ever tried one), they seem to have the worst fretwork ever. The only other guitar I have ever played with fret ends that sharp and uncomfortable was a friend's Squire. That said all the hardware on it is equivalent to the Prestige guitars. That part is important because the standard S series guitars tend to have softer metals. The threads inside the nut of my S470 stripped twice. Not a problem I've had at all with my RG2550 that replaced it and have had for like 8 years now. I genuinely liked the S series I had (stolen), beside that problem though.
