SW735  Bode Frequency Shifter Mark II

The model 735 Mark II is, like its predecessor, the model 735, a most sophisticated and powerful signal processor. In some of its typical applications it can change known sounds with a harmonic overtone structure into new sounds with an entirely different and new arrangement of overtones through additive and subtractive frequency shift. It thus contrasts with and complements the known pitch changers (such as the HARMONIZER), which operate with multiplicative frequency shift. At the MIX output jacks, a mixture of the OUT A and OUT B signals is obtained, which in the center position of the MIX control is that of a ring modulator. "...I remember my father telling me that he had completed building his new Bode Frequency Shifter Mark II. This was the unit he built for himself, for his own studio. Soon after, Florian Schneider of Kraftwerk came to visit my father at his home and studio. The Bode family were all big fans and collectors of Kraftwerk music. My father was happy for Florian's visit. He was not planning to sell and part with his new Frequency Shifter. It was a nice visit. He told me, a happy Florian Schneider left with the Bode Frequency Shifter Mark II under his arm."

Musical Applications:

As a keyboard-controlled instrument (1 volt/octave), the 735 Mark II is capable of producing an infinite variety of bell, chime, carillon, wood block, marimba, steel drum and other sounds, maintaining the chosen timbres over the entire playing range.

Due to a revolutionary new design of its patented local oscillator (quadrature oscillator), facilitating frequency shifts down to a fraction of 1 Hz (typically less than 0.05 Hz) the Model 735 Mark II can now be utilized for some very interesting ambience modulation effects.

Furthermore, when inserted in the feedback loop of a delay line, the ”spiraling echo effect“ can be produced. This opens upan unexplored variety of musical applications.
