I've had this set for just over a week now so I feel that I can give a fairly fair review of them.
First of all i'll get it out of the way that these aren't just the standard 81 & 60 in some flashy covers as most people expect them to be. I wanted a set of these for quite some time being a massive Metallica fan. Especially after hearing some newer live clips where James Hetfield has sounded amazing and cut through really well. From here on we can go into the main bulk of the review.
These pickups have a fairly high output which is to be expected as they are designed exclusively for metal and of course they are EMG pickups.
They have a great helping of upper mids which was a pleasant surprise with just the right amount of grind going on there. They also have a touch more low end than than the standard EMG pickups but it is still very tight and precise with absolutely no excess flub. The high end is very upfront but isn't grating in any way and doesn't fizz out.
These pickups don't dissapoint for clean sounds either. The bridge provides that classic james hetfield clean sound, think of the Master of Puppets interlude or the intro of Welcome Home. The neck pickup is even nice r and delivers some very soft yet punchy clean sounds that work really well for things such as fade to black or the intro to and justice for all.
Clearly Metallica tones are very easily achievable with these pickups as are tones from any of the 80's metal bands. If this is what you are looking for then you will not be dissapointed with these pickups.
These pickups look very slick with a very nice black nickel finish with individual ceramic polepieces on the neck pickup and steel poles for the bridge pickup.
Summary & Soundclips
Overall I am extremely happy with these pickups. I play Thrash metal primarly and these pickups can cover everything I throw at them with ease from Metallica right up to modern Exodus. Usually when I swap pickups out I have some bad points that really niggle at me which is why I left this review for a while and so far i can't find a single fault.
