I've been looking for a 7-string for a bit now, and someone offered me a nice deal on a K-7 with a pretty big battle scar. It's purely aesthetic so it doesn't bother me much. I've been an Ibanez guy for years, but mainly 6-stringers. Had an RG7321 for about half a year, and an RG8 for a couple of months, so I wouldn't really say that I'm well versed in the world of sevens. But it felt like the time for it, and the K-7 fits the bill great. Ibanez, Japanese, great trem, great reputation, low output passives, the works. But being the cautious buyer I am, I started reading up on the model as much as I could and then I stumbled upon that many people seem to feel a difference between the early K-7 necks and the later ones. Is there a difference, and if so, what do you prefer? The Ibanezes I have currently have Super Wizard and Ultra necks. Will the K-7 be akin to a 7-string version of any of those? Thanks in advance.
