Alembic has always been known for offering one of the best designed of all electróncias. In this case, the Essence takes two pills double winding Alembic model MXY56, and a well thought-mail system: we have a master volume, a balance of pills and a low-pass filter control is responsible for selecting the frequency we are enhancing (the amount of boost circuit is set inside by a potentiometer). Research carried out by Alembic led them to the conclusion that this control is the electronic equivalent closest to reproduce the waveforms produced by acoustic instruments, with its resonance characteristics.
