Title says it all. Has anybody done this? Curious to hear what it did for your sound, and how it affected your playing. I know the 85/15 is more of a full-frequency pickup (more lows, highs, etc), and the JB has a bump in the upper mids. The JB is a recognizable lead tone, but the 85/15 is no slouch either. The 85/15 does a great coil split, and the JB has a good reputation for that as well. So knowing these things, I'm curious about how anyone used the JB differently than the 85/15 in the same guitar.
