Thanks, some really great info there. I appreciate it. The A-bomb and Emerald combo seems to be what I'm after.
Oh, I don't play with any fancy equipment these days. I have a Fender Mustang IV v2 which perfectly suits my needs, and a Boss GT100 (surely a blasphemous setup around these parts) which almost is overkill with all the potential of the Mustang.
I used to have a 100w Peavey head, a 4x12 cab and a rather massive collection of pedals, but sold them all off when I realized I hadn't used any of it for a couple of years.
I also decided to just have one guitar, which I managed to do for a while, but now there's three of them and a bass.

Out of curiosity I checked out the Juggernaut, which I had dismissed as just too djenty. Lo and behold, it really sounds nice and versatile. It is of course a modern sounding pickup but I really enjoyed the sound of it. Especially with some overdrive the pups sounded surprisingly sweet.
Someone described it as a tighter Diver and although to my ears it sounds a bit wooly when palm muting, I'm intrigued by it.
After hearing the Juggernauts I now am contemplating not changing pups on the Chapman, but instead putting the money towards a Ibanez RG8 and trying out the eight stringed life.
I'm thinking if I enjoy it I'd upgrade the pups to Juggernatus. And if I don't I could just sell the RG8 and use the money and go back to the original plan - getting pups for the Chapman.
