Has anyone had the chance to do a comparison of the EMG's and the Duncan Blackouts to see which is better or what the difference in tone is.
Ive only had a very short experience with the blackouts (like 30min at a guitar shop :P) and i must say they have a much fuller sound than emgs. I much prefer the sound of the blackouts. Anyways just my 2cents

I have EMG's in my ESP eclipse and a Blackout in my Alexi Laiho guitar. Now, the two have different woods so the comparison might be a stretch. However here's what I'll say.

The Blackouts have sharper attack and have a more organic feel. Harmonics are well pronounced and notes articulate better. EMG 81 produces more gain though, and has a more powerful sound to it. I also prefer the EMG for clean, but that really might be because of my guitar wood (mahogany with emg, vs alder for blackout).

A lot of artists that used to use EMG are switching to Blackouts... Slipknot, that Dino guy (fear factory), Alexi Laiho (Children of Bodom). THe Blackout is a very nice pickup and is not at all "pwned" by the EMG 81.

i think blackouts have a lot more tone than EMGz, its really personal opinion though
blackouts are much better in my opinion. much "cleaner" distortion. it has less extra noise and feedback than the 81

emgs pwn blackouts. specially with the 18v mod

coming from someone who has metallica as their username. of course you're gonna say EMGs. I only have experience w/ EMGs. I haven't heard blackouts at all, so I can't say anything. Seymour Duncan is awesome though.
Save Gibson

^Do it, if you want Gibson to stop with the poor QC and terrible new guitars...
I still use emg's and so does thousands of pro's, i tried the blackouts and didnt like the sound of em

They arent drastically different enough to judge by asking UG, only way to find out is by testing them.
I have a 81 and i like it for most of things, depends what tones you want. If you want versitility, dont go for either, a good passive will be better.
