well i don't know whats going on but here's my input.
I have a MM with double allen head poles and I find this thing nearing my EMG 81 in output and has comparable harmonic content, slightly less, but the sound better and fuller although not quite as loud ( bearing in mind that the 81 is active!!) It has VERY tight bass, almost too tight for some things, and a very smooth mid output, that I think you might be perseving as not very high output as the PU is not to mid orientated.
The Fullshred if I remember correctly is VERY mid orientated and coupled with the fact that you have a mid boost, then to me it sounds as though you are just used to the fact of having tons of mids which can make a PU sound very heavy.
Tim and co. can correct me here but to my knowledge having alot of mid presence in a PU can make it sound louder than it might be and also the mid spike in your rig would start to overdrive an amp quite easily.
Anyway thats just my Idea. I wasn't sure what to expect when I got my MM, and to be quite honest, I wasn't that blown away by it when I first plugged it in (it was the first aftermarket PU id bought and I didn't have a huge experience with different guitars so I didn't know what I was listening for).
BUT after a while, you figure out how to get the best out of it.... and then you love it.
But as I said, it is comparable to an EMG 81, but with more bass and highs and less mid. but alot more dynamic and nowhere near as mushy.
If you think that it is based on Zakk who uses EMG 81's then its gotta be in that ballpark. why don't you listen to Tims MM clip on the players are of Miracl Man and then see if yours sounds similar?
