I came across this on a random filter search: http://www.planetbassonline.com/mm5...OS&Product_Code=Alembic_SF2&Category_Code=PRE It's referred to as a "tone processor" and the "Swiss Army knife of tone." I've read a lot about this, but I'm still not sure exactly what it does. It's apparently not an envelope filter. Is it a preamp, filter EQ, static filter, all of the above, or something else entirely? I'm asking purely out of curiosity; I won't be dropping $900+ on anything anytime soon! It's very intriguing, though; anyone have any hands-on experience with this unit?
