I have Juggs, A-Bomb, and Rebel Yell for bridge pickups. I have Juggs, Rebel Yell, and VHII for neck pickups.
Here's the thing: A-Bomb is really cool in a dark guitar like a Les Paul or a block of mahogany. It's tight for a 6 string in the range of E standard to Drop C ish. It does have a cut in the treble but it is a warm, organic sort of a tone with a pronounced AAAHHH vowel tone to the sound. Its gainy, hairy, and powerful.
The Rebel Yell bridge doesn't have a pronounced treble cut. It has a focus in the upper mids but with a very open and even top end. No frequency seems to cut or sizzle. Rather, it has a brilliant open sheen and the tone is open and huge sounding. The bass is high and very tight, so the pickup works best in a darker guitar with a lot of low mids. It can sound overly bright and anemic in a bright guitar.
The Juggernaut pickup has huge and powerful low mids, a tight bass response, and a diffuse / purring top end. It does have a nice pick attack and cut in the upper frequencies but this quality is quite blunted.
The set is amazing and I personally prefer it with an Ibanez style 5 way blade switch. This gives me neck in series, neck in parallel, bridge and neck in series, inner coils, and bridge in series. With a treble bleed mod, you can use the volume pot and access many really awesome tones.
I'd say that this pickup set works best with really bright 6 and 7 string guitars. Any guitar that is really bright work spectacularly well with this pickup. If you have a brighter amp a more balanced sounding guitar can sound great as well but then you end up with a darker tone overall.
Let me know and I can PM you some scratch tracks I was using for songwriting. You can at least hear how the pickups sound. Do keep in mind that they are in guitars that are optimal for the best result in all cases.
