Tetractave Analog Octaver

FTelettronica is an Italian one-man shop in Isola del Liri, founded in 2008. They build faithful clones of rare and discontinued effects, using Alpha pots, Neutrik/Lumberg jacks, and a 2-year warranty.

The Tetractave is a monophonic analog octaver with four selectable modes: 1st Octave Down, 2nd Octave Down, Upper Octave (1st up), and Clean (unprocessed). 24mA, 390g, 125x105mm, powder-coated. True bypass.

Four modes in one footprint. The 2nd octave down produces a massive sub-bass rumble. Upper octave adds the characteristic analog octave-up ring. Clean mode lets it work as a tuner mute or simple bypass.
