Just got back and plugged in with the JB. First impressions after 10 minutes without changing anything on my preset. It does sound a little thin when playing chords and it's not as 'dirty' as the Super D. There is some girth missing. The trade off is that when solo-ing, it is more articulate and fluid. It also takes boosts and even a stacked boost better. The JB is notorious for being mid-voiced and it is. I will most likely go back to the Super D because it seems to fit the guitars tone better. But I'm only 10 minutes into it and I've yet to tweak my preset to fit. I may flip-flop after I change the input EQ curve's range and boost and dial in a 'fuller' tone.....assuming I can. I think anything is possible with the AxeFx3 so this pickup chasing thing is sort of not needed. But I wanted to know. I may end up throwing the JB into one of my other guitars for fun.
