Oh my... If that poor guitar could talk!
It probably did not come with EMG's or it would have a separate battery cover on the back of the guitar. I have put EMG's in an RG style guitar and had to cram the 9v battery in the control cavity, so it can work. If you want to use them you can pick up a used EMG SA single coil. They have good wiring diagrams on their website too. Looks like those are the 81/85 (aka Zakk Wylde) set maybe? I used the same set and kind of liked them. Keep in mind that if you use the EMG's, you want to make sure the previous owner changed out the pots to 25k.
You can probably pick up a used 24 fret neck pretty reasonable from ebay or the like. Not sure which neck that is, maybe a Wizard II? Are there any serial numbers on the back of the headstock? I'm no luthier, but I think any modern AANJ 24 fret Ibanez neck will bolt up there. You may have to shim or tweak it to fit well, but that is normal for any guitar.
If this guitar could talk it would scream for help
I'll keep the 81/85 EMG pickups initially, but I will definitely have to redo the wiring, change the pot as you said, etc. it's a complete mess.
There's no serial anywhere. I am thinking this could be a RGR-470. It would make sense with the faded numbers I found in the neck pocket (<scratched dirt>GR - <1 or 4>70), the reverse headstock and bits of blueish paint remains I found inside of it. And the body, neck, etc looks very similar. But of course it could also easily be a GRG-170 body.
Rhe main problem right now is I really don't t know if I should go for a Wizard or Wizard II neck. The dimensions on this one are:
- Width at nut: 43mm
- Width at last fret: 57mm
- Thickness at first fret: 18.5 to 19mm (irregular depending on where the caliper is placed, I guess as a result of the neck being so twisted)
- Thickness at 12th fret: 20mm.
So I guess it could be a Wizard or Wizard II, depending on the year.
With this measurements, am I wrong to assume that any Wizard or Wizard II aanj neck will probably fit?
