Just spitballing here, so on a 5 XXX, why couldn't the PUPs all be wired in series, and be independently turned on with their own DPST switch instead of the 4 way rotary (please bear in mind I know little about electronics if this is a stupid question )? I know someone was looking into a 5 way rotary, maybe if Sheldon & company ever catch their breath they can work on incorporating one for use in 3 PUP applications?
The 4-way rotary works great for 2 pickups but without individual series/parallel switches for each pickup I found the tonal range on my NG-2 a bit limited. I had the 50K bass and low mid pots on the Darkglass pre replaced with ones having a DPDT switch. Push/pull on the bass pot for parallel/series on the neck pickup and push/pull on the low mid pot for parallel/series on the bridge pickup. This has really opened up the tone combinations on this bass in a good way. There are now 12 combinations to choose from instead of 4. The neck pickup in series with a bit of 500 Hz boost has a great P-bass vibe with a little less honk and a bit more focus - probably my favorite tone now. Neck and bridge pickups series with the pair in parallel, slight 500 Hz cut and 2.8 kHz boost is also a winner. These two also balance volume-wise with neck and bridge pickups parallel with the pair in series. Very pleased with the results, it worked just as I hoped. Loving that NG-2 now! I seriously think this is good enough to consider as a standard option.
On a 5 XXX, individual series/parallel switches for the 3 pickups could be used in combination with a DPDT switch to select either neck or middle pickup to feed the 4-way rotary. This would allow any of the 3 pickups to be soloed and parallel or series alignment of neck or middle with the bridge. Use of a push/pull pot with DPDT switch avoids having to drill another hole.
With neck pickup routed to the 4-way you'd have:
- neck soloed (parallel or series)
- neck and bridge in series (parallel or series for individual pickups)
- neck and bridge in parallel (parallel or series for individual pickups)
- bridge soloed (parallel or series)
With middle pickup routed to the 4-way you'd have:
- middle soloed (parallel or series)
- middle and bridge in series (parallel or series for individual pickups)
- middle and bridge in parallel (parallel or series for individual pickups)
- bridge soloed (parallel or series)
Having owned an ABZ-5 and now an NG-2, the shifted neck pickup position does matter and they are two different flavors of good. I'd like to pursue the configuration just described because it's a relatively minor modification from what is currently offered with the 3X option and adds several alignments which would be quite useful. If not configured at the Dingwall shop it could be a relatively minor aftermarket modification.
