Distiller

Having owned several Alembic basses, I have found their electronics to be truly special. Unlike most other basses using passive tone controls or conventional 2- or 3-band EQs, Alembic basses come equipped with a unique 12dB-per-octave low-pass filter that features a widely adjustable cutoff frequency and a resonant peak just before the cut. With just one knob, you can access a very wide range of tones, from the darkest dub and reggae sounds to the brightest slap and funk tones and everything in between. 

While synth players routinely use resonant filters, they are not common among bassists, who may only encounter them on a few high-end, boutique instruments.

Compared to the original Alembic filter, the Distiller offers longer battery life, lower noise, and adopts a standard grounding scheme that makes it compatible with virtually any bass. It can also be easily installed in a pedal if desired.
