Finally, I can add input to a tone question! :D
Well I play through a Savage 120, and I have Painkillers in my custom Mahogany body, maple neck, rosewood fretboard; and I absolutely adore my tone from my guitar. I would highly recommend the Painkiller.
It looks like we go after the same kind of sound. I like a lot of cut, and clarity, but I need some sizzle, at times. If you play technical, with any amount of harmony and lead work; I think you will love this pickup. Open chords have that perfect clarity and cut; and you get endless, shimmering sustain.
This pickup isn’t for everyone, but I think you might like it a lot. When you push the tubes on the Savage, and combine this pickup into the mix, it is a beautiful thing!
The painkiller is the only BK that I own, but I have a Ceramic Warpig on the way (for another guitar); and I will be ordering a Ceramic Nailbomb HSS set with Sinners (for yet, another guitar); so if should have something to compare to in a couple weeks.
If you have any questions about the Painkiller, or how I set my tone on the Savage let me know and I will be more than happy to offer my input. 8)
Cheers!
