So I finally got around to swapping that ceramic magnet into the Nailbomb & boy oh boy, is it staying. Everything about the pickup improved immediately & I love everything about it now. The bottom end tightened up, the note clarity & string separation under gain improved, pinch harmonics are much easier to pull off & best of all, after a bunch of A/B listening to recordings, the treble strings really don't seem to be any sharper than they were with the alnico magnet.
So then, the winning combo for the Ibanez RG570 was a C-Bomb in the bridge & VHII in the neck. I A/B recorded & listened back to my other 6 strings (.strandberg* with Juggernauts and a tele with Piledrivers) and I think the Ibby might not only be my favorite for the main tones I play, but also now the most versatile. Stoked!
