Compound radius fretboards

[adriandavidb]

Not sure if this topic should go here, or in the JS thread?

The Ibanez website states something that suggests that the 'Prestige' necks are fitted to all but the 'bog-standard' (cheapest) JS, are equiped with compound radius fretboards i.e the camber radius increases from nut to neck, to facilitate string bending at low action heights, without 'choking-off'. Is this the case?

Also do the wizard necks fitted to other Ibanez guitars have them too?

The JS necks are multi radius, but that refers to the BACK of the neck.

Compound radius means the fretboard itself starts off with a small, more curved radius at the nut, and flattens out going down the neck, to faciliatate lead playing further down.

Ibanez generally do not produce compound radius necks, preferring to stick with a constant radius all the way down. On wizard necks that will be a 430mm radius, so very flat. On a JS neck, it will be a little wierd all over, since those necks are digital recreations of Joes favourite time worn neck.

Could someone please explain how the radius is measured?

I understand other manufacturer's neck radius specs, eg. Fender where a 9" radius means the curve of the fretboard is the same as an arc of 9" radius circle, but have no clue how the flat neck of an Ibanez has a radius of 430mm!

Sorry for being off topic.

The JS neck has a compound radius on the fretboard and multi radius on the back of the neck.

cos ibanez necks arent quite flat, they have the same curvature as a circle of radius 430mm...
obviously, a circle that big is going to seem quite flat over a section as small as the width of a fingerboard.

The metric system?????

430 mm is ~17 inches . . .

GuitarBizzarre, I know very well what compound radius means, as you can see from reading my post, I mention fretboard, NOT the back of the neck! Thanks for your input anyway.

jb4674, any idea what the variation in radius is from nut to to top end??

The compound radiusing and "digitized" marketing is about the back of the neck only. The fretboard is 250mm radius 1-22.

This belongs in the JS forum.

Wow, how embarassing. My (at the time) fried brain led me to believe that 430mm = 4.3cm instead of 43cm, hence the confusion!
