Re: my friends say there guitars are better then my rg570ct is it true?
Yep, sounds like an absolutely killer guitar for $400. I would take an alder RG any day of the week.
It is not unheard of for cheap guitars to be great, or vice versa. A guy who works in my local guitar shop swears by his knackered old Squire strat. He is an amazing player, so I trust his ear more than mine, but he one of the very few people I can say that about. I think that one of the most important thigns with cheaper guitars (i.e. less than $1,000) is the factory that they were made in. I think that it is fair to say that the Japanese RG's were of a consistently high standard and come from the Fujigen factory, where a lot of companies get their guitars made. I think that the Fender HM Strat was also made there and they are good. The only thing that lets the RG down slightly is the pickups, but even then compared to a cheap squire
Most important of all: many guitarists think that there guitar is the best ever made; is worth much more than they paid for it; and is better than any guitar anyone else has. This is entirely normal and nothing to worry about. I once had a guy swear blind that he had exactly the same guitar as I was holding at the time, which happened to be a custom paduak RG which I had made myself, with reverse headstock etc etc etc. Even when I told him that I had personally glued the body blanks, cut out and sanded it in my back garden he still insisted that he had the same guitar.
The bottom line is that you have to trust your ears and your fingers when it comes to guitars. It is your opinion that should decide what is best for you, and as I say, guitarists do that kind of thing all the time, you might as well get used to it.
