For reference purposes, here is what the stock NG-2 has wired and what the stock NG-3 has wired. In the NG-2 to NG-3 conversion, the there is no "neck" like the NG-3, because there is no pickup in that position. So, "neck" on the NG-2 is "middle" on the NG-3.
Here's how the NG-2 is wired:
- Bridge
- Bridge/Neck in Parallel
- Bridge/Neck in Series (Not in the NG-3 switch)
- Neck
Pickups are in the bottom two positions. Neck is empty.
And how the NG-3 is supposed to be wired:
1(Bridge)- Motown fender tone. (Same as position 1 above)
2(Bridge/Middle in Parallel)- Fender J tone (Same as position 2 above)
3(Middle)- Stingray MM tone (Same as position 4 above)
4(Bridge/Middle in Parallel + Neck in Series)- Dingwall tone (Unique to NG-3)
I've got the 6-way switch mentioned above, but I haven't installed the NG-3 upgrade OR the switch, yet. I thought I'd get real familiar with the NG-2 first, then start experimenting.
