Background: I'm coming back to my 5420T after 18 months of a Telecaster. The Gretsch sounded dark: darker even than I thought a hollowbody should sound. (Not that I've played enough different guitars to really know.) I thought about getting TV Jones pickups, and maybe I still will, but I'm trying hard right now -- for spiritual reasons -- to explore what I have instead of pile up more. I have read so many good things on this forum about Black Top Filter'Trons that I thought, "There must be something I can do to make these sound better." Last night after a movie I screwed all of the poles down to the level of the black plastic (and wiped away the wax that came out when I did). Then I cranked both pickups up as high as they could go. When I measured from string bottom to black plastic, they ended up being a little closer to the strings than the TV Jones recommendations. (Earlier in the week I had adjusted the pickup heights to TV Jones specs, but measuring from the top of chrome covers, which are higher than the black plastic. Result: the actual pickups were probably farther away from the strings than TVJ suggests.) With the pickups jacked up to maximum height, I'm getting more volume (no surprise) and more articulation (coming from Fender single coils, this is a surprise). I'm also hearing, I think, some compression now from the amp. (The clean channel on this amp is hard to overdrive into distortion, but it can get warm and round: that's what I'm hearing now.) Any thoughts on adjusting the poles? I know I can use them to adjust individual string volume, per the diagrams on TV Jones' website. But what is the difference between raising the pickup and raising a pole? And why are there two poles per string on each pickup?
