theyre beautifully sparkly. First neck pickup i've had that isnt muddy as shite. I can go from a decent clean to awesome gain. The clean sounds somewhat accoustic, not very fat (which i can attribute to my amp), but very sparkly, almost fender twin reverb sparkly. I plug this thing into my marshall 30th anniversary head and play anything from progressive punk (fall of troy, circa survive) to stoner rock (like the Sword, High on Fire, Open Hand) to hardcore and death metal (Between the Buried and Me, Job for a Cowboy, Dark Tranquillity, Bloodbath (with a boss HM-2 of course...) It has all the gain without the muddiness.
My other guitars are a bc rich JR. V with emg 81/85, and an ibanez RG stock.
They do not have as much output as the emg's, but they have essentially the same amount of bass with slightly looser attack (to be expected when comparing passive to active), and a bit more trebel. They arent as sterile and hollow sounding.
Compared to the ibanez stocks, theyre WAY tighter, alot more output, and have slightly less bass, and a bit less mids.
I've had a problem though with old pots, and i took them into a tech who replaced them with 250k's instead of the standard 500k, which cut off some of my trebel and adding a bit of darkness. I'm upgrading to 500k once i have some free time so i can get its true tone back.
The only thing i find it lacks is a bit of punch and mids, but its amazingly clear and articulate.
