More clank, indeed! I just installed the guitar high gains and they sound pretty darn good. I won't get overly exuberant, but it's a noticeable change and, to my desires, improvement over the HBs. Not slagging the HBs, just that this is more the sound I like. And to get the single coil sound on the Cii body is quite pleasing.
They were a bit weak on first blush. I'm speculating a combination of where the pole pieces are now in relation to the strings and the body composition. I adjusted the new pole pieces (flat hex screws, 8-32 3/4") a bit higher, added a little more drive to the preamp, and *poof*! Lovely sound. I'm actually back to where I was on my drive setting where I used to run with a 4003. The HBs didn't want as much drive to sound good. Again, it's just a hair off from sounding exactly like the 4003, close enough to be convincing, and just enough difference in sound to be unique from the 4003 and 4004. Did that make any sense?
The B and G strings do lie outside the pole pieces, but it does not appear to make a difference compared to the other strings. They're all equally potent. The next test is with a full band in the room this afternoon.
