No responses here but I've gotten a bunch on The Gear Page, in case anyone's interested.http://www.thegearpage.net/board/showth ... ?t=1402296
One observation I will make about my own guitar with these characteristics:
>> In the guitar of mine that prompted my questions, the bridge PUP is a Dimarzio Super Distortion HB, the middle and neck PUPs are both Dimarzio Super 2's, all are oriented north coil neck side/south coil bridge side, and I've wired them with 3-way minitoggles to give me north coil-both-south coil. The north coils are essentially where Strat PUPs would be. The south coils are very close to where the north coils were on Jerry Garcia's custom guitars. This appears to give me BOTH classic Strat AND Jerry tones in the same guitar.
There is a huge difference in tone between the two coils in the bridge and neck positions. The difference between the two coils in the middle position is also noticeable but far less significant.
From this I'm deriving that if you're guitar of choice for Jerry tones is a straight up Strat and you live on the middle pickup, you're at least 90% of the way "there." Not so, though, when you select the bridge or neck pickup.
