I need some opinions on the Ibanez RG7421. Are they MIJ? Are the necks the thinnest of the wizard 7 necks?
I've been wanting to pick up some kind of nice Ibby 7 here lately, preferably with a fixed bridge. And, I spoted one of these pretty cheap.
They are the thinnest if it has a bubinga strip. The 'solid' all maple necks were slightly thicker and taken from the RG762x. I've never seen a 7621 neck on a 7421, but I haven't seen many 7421's.
They were all MIJ.
Given the choice, I'd go for a 7421 over a 7621. They were functionally identical, except the 7621 came with a few extra colour options, a different bridge, and those god-awful Dimarzio New-7's.
The 7421 came with an in-house bridge (it's fixed, it doesn't move, it works - what more do you need?!) and god-awful in-house V77 and V87 pickups.
Either way the guitar will need a pup swap, but I think the 742x necks were better and the different routing on the 7421 means fitting replacement pickups is much easier.
