Differences: Radius 440R / 540R ?

[jazzedout]

I have found a nice (1990 I think) black 440RHH with the 3-way switch. Is there any other difference to the 540R except from pickups and diferent inlays?

Do the Radii 440 have the Ultra neck as the R540? Anyone?

You can find the catalog description of the 440R/540R in the EU catalogs on the Ibanez site:

The 1990/91 catalogs don't specify the neck type for either model. Seems like the main difference was the V pickups instead of the IBZ's in the 540R, and in 91 Edge instead of LoPro trem. All it says about the neck is "maple: 1 piece" but I'd be surprised if it's not an Ultra.
