Re: Lace Drop and Gain?
I actually use them on a guitar in standard E, and I really like them (I play mostly thrash metal). They're great for this sort of music, because of their immense clarity and definition, even under really high gain; hence why they're marketed for drop tuners.
Dynamic range is excellent - being passive, there's no limit on headroom. They'll give as much or as little output as your right hand can. I've read someone else's description of the harmonics as very "glass bell-like", and I'd agree.
The bridge pickup has the most cut, and is brilliant for aggressive riffing or soloing. The neck pickup is much fatter (kind of an overwound PAF), good for clean arpeggios or smoother solos. (Of note is that the bridge and neck pickup match very nicely in volume.) The only real weakness is that when playing 5 or 6 string clean chords, the neck pickup can be almost too fat - clipping can become a problem. I generally use slightly compression on neck cleans for this reason.
Basically, I think they're a great combination of the characteristics of EMGs (especially the definition) and passives (dynamic range, slightly more organic character, especially in the neck). I think they're perfect for metal, and certainly drop-tuning.
Let me know if there's anything else I can answer
