My 7-string guitar journey began quite recently, only within the past few months but I'm absolutely hooked. I currently have an Ibanez RG-7421 MIJ from 2000, and a Music Man JP7.

I bought the JP7 after playing a Sterling JP70 at a Guitar Center and found the neck absolutely perfect because of its full-bodied roundness, it filled my hand perfectly. The Ibanez by comparison, while thicker than some other Ibanez models I've played, is still traditionally "Ibanez" and quite flat/thin overall.

I shouldn't be surprised, but I am a bit disappointed that the Music Man JP7 neck profile is quite different from the Sterling JP70 - quite flat/thin overall and not much of a departure from my Ibanez RG7421. I plan to likely circle back around to the JP70 because I liked the neck so much.

Meanwhile, I've been researching Ibanez neck profiles for their 7-string RG models on the Ibanez Fandom Wiki, searching for what would be the fullest/narrowest 7-string neck profile. It would seem, if the info can be considered reliable, that the thickest/narrowest Ibanez 7-string neck profile is the "RG7" profile (correct me if I'm wrong). However I can't seem to figure out what model is associated with this neck shape. The wiki seems to indicate that the RG-7620/RG-7621 has the "RG7" neck profile however the yearly Ibanez catalogs only indicate it as a "Wizard" neck shape.

Then there's the matter of whether you find one with the all maple neck or the 3-piece maple/bubinga/maple necks - from what I've read it seems the all maple necks are slightly thicker than the 3-piece necks which would stand to reason, as making a neck out of separate pieces of wood usually results in increased stiffness, which is needed with a thinner neck profile.

If anyone has any experience or knowledge to share, on which Ibanez 7-string guitar models (preferably RG shape) would feature the most thick and narrow neck profile, I would really appreciate hearing it!

My 98 7620 neck is definitely thicker than you’d expect and narrow. I’ve gone back and forth on what I “feel” in the necks, I need to go get a contour gauge and take some actual measurements lol, definitely thicker and narrower than my 752 neck.

I think this is the opposite of what anyone would think an Ibanez would have
There's a difference between wanting a "thick/narrow" neck vs what is "thickest/narrowest" relative to other models in a lineup.

Good to know - maple neck or bubinga stripe on yours?

I have a maple, 3 x three piece maple bubinga and a five piece maple walnut. I'll measure with calipers when I can.

All the wizard 7 types I;ve played from 7620's J custom, Prestige etc. from 97 onwards are either one of two types, even amongst the same models and years. They're either thin with wide shoulders, or thicker with more rounded shoulders.

The 7321 that is currently on my FRG7620 in my Avatar to the left is definitely thicker than the stock ‘98 7620 neck that came with the original 7620. The 7321 is also a 5 piece neck shaft where the 7620 is a two piece.

Going to measure my 98 7620 and 2015 752fx when I restring next, I'm curious to see the variance in neck thicknesses!

I'll throw an oddball in there... The Gio.

I have a Gio I pieced together that is super chunky compared to my 7321's/7420/1527 RG's. I'm not sure on the width but I feel it's comparable to the other guitars but way thicker. It's comfy and plays really well.
