I have it on good authority that Alembic and EMG electronics operate at different voltages (or something) and are fairly well incompatible, so I would be surprised if the guts were intact.
Jim--Alembic pickups sound roughly similar to EMGs, being based on ceramic magnets (correct me if I'm wrong on this, please), and have what's thought of as a hi-fi tone. The difference, and the beauty, is in the electronics Dave referred to--rather than a straight treble rolloff or bass and treble boost, Alembic tone controls emphasize a certain peak frequency in the tone spectrum depending on how the tone pot is set. The easiest way to explain it is as similar to rocking a wah pedal with a wide range through its' path of travel until a favored tone is found, and then leaving the pedal in that position. This allows a wide spectrum of midranges tones to choose from.
Make sense? I hope so...that's about as well as I can explain it!
Congratulations, and welcome.
