EMGs - either you hate them or you love them.
I personally think they are great. The 81 is perfect for anything with al lot of gain in the bridge position, where i find the 60 is the one you want put in your neck postion.
Though many people prefer the 85 in the neck for shredding solos, the 60 is perfect for the really smooth, singing leads. Although you can shred with them just as nice, if you ask me.
But the one thing that really stands out for me with this pickup is the clean tone.
It has a very bright, shiny, natural tone, almost a bit like an acoustic guitar.
If you are into clean arpeggios with some chorus and delay, with the EMG 60 you'll find yourself in 80s metal intros instantaniously.
The quick-connect system is a nice thing, too. Although I am not reluctant to soldering at all, it is really the easiest and fastest way to wire up a guitar.
The downside is that you must use all the cables with the length they come with, which can lead to a bit crammed up rear cavity. That is especially annoying when you are retrofitting EMGs in a guitar that has no extra space for the battery.
But in this very case you can always cut the cables to the needed length and go back to soldering again. The little circuit board provides extra soldering points for that (or if you want to combine it with an older EMG that hasn't got quick-connect).
Seems they thought of everything at this one...
