Well, after thinking I was settled on replacing stock Combustion pups with FDVs, then thinking I preferred SFIIs, I came to terms with the fact that I haven't ever really liked most clips of the SFIIs and the FDVs sounded shrill or anemic sometimes.
I wanted less low lows and more mids for the SFIIs, but more low mids and high lows in the FDVs. So I bought a set of FD3s
I recorded finger and pick clips of the FD3Ns in a number of configurations since I have two rotaries and three S/P toggles, and I just installed the neck FD3 and recorded a comparison clip.
A Dingwall rep told me to not get the FD3s because they were virtually identical to the FD3Ns. My ears disagree. Going off the neck pickup alone - it's more articulate (i.e. more treble content that's not shrill), refined, less boomy and muddy. In comparison, FD3Ns are causing ear fatigue quickly.
Something I haven't seen anyone talk about - the Canadian pups are much lighter so I'm happy for the weight benefit too.
Edit: Import 6 string pickup is 155 grams, or 5.47 oz. Canadian is 120g or 4.23oz. Over three pickups that shaves off 3.7oz, almost a quarter of a pound. Not a whole lot by any means, but it's a nice bonus
