Re: outer "current coil" effect at play..?

Richard,
The sweet spot I have landed on for the George L humbucker, is pretty exact center bridge to center PU = 70mm. Then I have around 4-5mm further to go, to 75mm, and can reduce around 15-16mm to 54mm.
For exactness: the bridge/changer is skewed 3mm from high to low string on that PSG - low strings are longer like on a regular guitar, so I measured bridge/PU distance between string 5 and 6.
More than +/- 2mm lengthwise from the sweet spot produce audible but not dramatic tone-change, and the 65 to 72mm range sounds well balanced.
Less than around 62mm sounds increasingly sharp and is great for certain tunes - el-guitar or "old fender" sound. Don't go to minimum very often and usually not for long.
Max distance: 75mm, is where the strings/PSG start to sound a bit too rich and round for my taste, so the cavity is long enough. No dramatic tone-change from the sweet spot, but after a few tunes in that position I tend to push the PU back to 70mm.
My regular sound chain here in Norway (where I keep the modded Dekley) is short cable > LMB-3 > VP > NV112 with EQ stage bypassed. Bypassing the EQ means I also bypass what I interpret as a high-pass filter in the EQ stage's input, so my NV112 goes a tad deeper and more evenly into the sub-bass range than normal.
