I bought 2 Ibanez RV-470's earlier this year, and just picked up an extra Body last month, but was having a difficult time finding a suitable neck. I had no replies from emails sent to ETGuitars, Bunker, or PerleGuitars on availability of 22 fret AANJ neck. Only Ed Roman confirmed the availability of a 22 Fret AANJ neck, but before I decide to send my body off to Vegas, I want to give these other companies more time to respond, and went with a different approach.
I found a used S series MIJ used Ibanez neck, that had the AANJ, and 22 frets, and rolled the dice that it would work. These necks occasionally can be found on auction sites, and are reasonable priced, but always are routed with a shelf for locking nut, which is NOT what I want. However, I purchased a conversion nut from PerleGuitars that fits in the Shelf route, and is cut for 10's.
It fit perfectly. The neck is wider at the nut and has a different radius and profile than the Vipers on my other RV-470's, but it fits the neck pocket like a dream, and bolted in with no issues. It intonated on a dime, and after adjusting the bridge to match the radius, it plays wonderfully.
On left is RV with replacement neck from S Series, on right RV with Viper neck.
Far left before I installed the pickups in the new Rv, to the right the other Vintage Tobacco RV-470,( with a Dimarzio Bluesbucker in bridge, Dimarzio Cruiser in middle, and Dimarzio Eric Johnson in neck, and a Wilkinson VS 300 trem), then a 442R I picked up a month ago, ( and added cream Dimarzio True Velvets and cream/black Bluesbucker, and a Goeldo Backstop), a Trans Purple RV-470,( with Dimarzio Andy Timmons in Bridge, stock middle, and Bluesbucker in neck) a Royal Blue BL-550 Blazer, and a White 430 S,(with Goeldo Backstop) both with stock Single Coils. The ibanez single Coils from the 80's and 90's are incredible ! The Blazer has the coils tapped, so you have the option of a vintage tone, or a tone a bit hotter, and also in position 2 and 4, you can have the two single coils operate in parallel or series humbucking modes.
I still have all my RG Prestiges with Edge and Edge Pro's, and sure don't plan on parting with them, but obviously I have found an admiration for Guitars with vintage trems lately, and IMHO, The ones from Ibanez are the best !!!
