Cornucopia - Tube overdrive
Tone color, presence, musicality: these are the most important featu-
res of Cornucopia tube overdrive. We didn't simply placed-in a tube;
the overall sonic performance is due to the synergy of operations
from each circuit section. Hum, noise and performance degradation
can rapidly come if even a little part of design process is not carefully
controlled. Cornucopia comes out from many time spent in designing
and engineering. It's only with this rigorous design approach than
the 12AX7 can give the best sonic performances, symbolized by the
Cornucopia in the hand of the deity Tiberinus.

CORNUCOPIA Operating Manual
The strong 12AX7 personality, controlled and regulated by other ori-
ginal J-FET circuits, provides a "tube colored" tone even in transistor
amplifications, setting Cornucopia to a quasi-clean boosting only. For
this reason, we consider Cornucopia more like a miniaturized pre-
amplifier to place in front of amplification that needs more "tube-ish"
sound. For highly saturated sounds, turn full CW the Gain know and
you get the angrier tone ever on a tube preamp. The "Bias" command
enhances its versatility of use, changing the operating conditions of
12AX7 to obtain a dirtier distortion, but keeping the musicality, ac-
cording to the most important rule in whole Tefi Vintage Lab desi-
gns.
