The Warmth Generator on the UBK Fatso softens and saturates the high frequencies of your signal in a way that evokes the spirit of analog tape and classic tube gear. As usual, its operation could not be simpler: with each press of the Warmth Generator's single button, you increase both the intensity and the audibility of the effect. 7 discrete threshold levels give you a range from 'subliminal' to 'excessive' and everything in between.

When used subtly, the Warmth Generator adds a touch of that old school analog magic we all lust for. But Warmth also fixes problems that we all deal with far more often than we'd like: it smooths harsh, brittle drum overheads, it softens brash sibilant vocalists, it rounds out the edges of an overly bright, metallic sounding acoustic guitar, and it de-digitizes grainy drum loops.

With the UBK Fatso in your rack, a world of vintage tone and fatness is at your fingertips.

The transformer circuit in the UBK Fatso was specially tuned by Dave Derr to not only produce these desirable artifacts, but also to replicate 'head bump', the name given to the low end weight and inherent eq boost that happens whenever you record on open reel analog tape decks. Simply by flicking a switch on the UBK Fatso, your bass takes on a little more growl and grit; it also becomes more audible and full-sounding on smaller speakers. Acoustic guitars take on a shimmering quality, drums and vocals have a touch more air and presence.

Be aware, as with all good circuits the transformer coloration of the UBK Fatso is not a radical effect, it is in fact what I would call 'subtle'. But its effect, especially as it accumulates on many or most of the tracks in your project, can be very powerful indeed.
