After many changes on my guitar pickups, seymour including SH4, and very good Prs hfs, and emg 81, I must say that I finally found the microphone I was looking for!
I play progressive metal, so I needed a powerful and aggressive pickups for rhythm, very precise, ie restoring good attacking each note in the solos, and last but not least, a microphone with the character, which I do so its not a cold and soulless. Well the crunch lab, micro current Mister Petrucci, meets all these criteria. In my mesa boogie rhythm on it's pretty close to the roar of a lion) solo with a good setting, the grain is fabulous very clean not mushy, but with much harmonic richness rich medium, and low. As I always clean paired with his friend the liquifire, but it does not handle so poorly in this area.

Voila! In summary I'm really happy with this microphone that I use also currently in the studio. I add that I could also compare it to my amp with the musicman ernie ball Petrucci first version equipped with d-sonic, well I think the lab is the crunch point, I consider it an improvement in the d- Sonic, richer bass, and meaner
