Hey Edo.
Definitely hotter than the CS69's. The AIWIY clip I did, has the Input Drive higher than your IRIS settings and I also used the SDD in front of the amp.
I wonder though if the FS-1 is unwound, like Dallas (or maybe Edge) mentioned in an article years ago? If I recall, there is a way to measure the resistance of pick-ups in a Strat, without removing them...(Google search)...Yip...there is! It works too, just tried it on my Strat;
"Here's a fast way to measure the approximate (within a couple of percent) DC resistance of your pickups without having to take anything apart on the guitar. All you need is a multimeter and a patch cable. Insert the patch cable into the guitar, turn the guitar's pickup selector switch to activate the pickup you wish to measure, turn the volume pot all the way up, and then contact one meter probe to the tip of the exposed cable plug and the other to the shaft below the insulating ring. You've now completed a circuit through that pickup and by turning your multimeter to the expected resistance range (I use the 20K range setting on my cheapo Rat Shack meter), you'll be able to read the pickup's resistance."
