Re: why do ibanez call their guitars by a code?!?
It used to be a lot simpler in the "pre-prestige" days, an RG770 was better than an RG570 which was better than an RG470 etc etc etc.
And taking Gurj's example, very much like the BMW code, 330 is a small saloon, with a big engine, wheras a 520 is a big saloon with a smaller engine etc etc.
I'm just getting used to figuring out what the codes sort of mean again. But I think once you know what means what, alphanumeric codes tend to be easier than dungeons and dragons style names!
