Re: RG550RF vs RG655FSO opinions & thoughts?
I'll just assume we're talking about the 20th Anniversary RG550:
I just replaced my RG550MXX RF with an RG2820, so I can't comment on the 655, but I will say this:
I was originally going to replace the 550 with the 655, but after looking on Ikebe Gakki I found the 2820 and couldn't not buy it.
The AANJ heel on the 655, for me, is the number one advantage it has. I think the 655 is a superior guitar because of the fretwork also. I think Ibanez started improving their craftsmanship after 2010 or so.
I don't like the FSO colour, so I would get the Cobalt Blue Metallic one!
My RG550 was still an amazing guitar. I got it for 650 USD so it was a steal. The frets had that basic edge treatment that is reminiscent of Ibanez stuff from the 90's, and they were crowned just as good as the newer stuff. The only difference is the fret-ends.
Also the 655 comes with DiMarzios right off the cuff!
In terms of price you can find the RF for cheaper than a brand new 655, but I'm a proponent of buying new, so that's another reason I'd recommend the RG655.
