CORNUCOPIA Keys – Tube Overdrive
by TEFI Vintage Lab
Effects: Overdrive, tube preamplifier
The Cornucopia Keys project was developed starting from the Cornucopia Guitar with the idea of obtaining a preamplifier with 12AX7 tube specifically dedicated to Tonewheel organs (Hammond), sixties Combo organs (Farfisa, Vox), Electric Pianos (Rhodes, Wurlitzer) and Synthesizers . Unlike the electric guitar, a keyboard instrument indeed requires a much wider response band, in order to totally preserve the harmonic content of the signal, and also requires a reduced dynamic field when entering overdrive conditions. By bringing the Gain command to high values, you can get a creamy and characterized overdrive from the Cornucopia Keys, retaining high sonic transparency that behaves exactly like a tube amp when a large signal is applied in. The Volume and Gain commands allow you to adjust/match the input levels with output and choose the point where you want to trigger the overdrive, while the Contour command can set a first general equalization of the sound. The Bias lever-switch acts on the tube bias and allows you to choose two different overdrive behaviours: creamy in "Soft" position and fuzzy in "Hard" mode.
The working of Cornucopia Keys has also been tested on clones and current emulators (digital, analog and vitrual analog) of keyboard instruments. Thanks to the high bandwidth, the Cornucopia Keys can also be used as a characterizing preamplifier, or in light overdrive, as an enhancer of harmonics in the treatment of a track (even drums or voice) during the recording.
The power requirement for this is 12VAC/1000ma, a power supply is included but at the moment has a Euro plug on it so if you are in the UK you will need one of those shaver adapter thingys!
