An expanded and modernized take on the Colorsound Dipthonizer filter.

In the late ’70s, Colorsound briefly produced an envelope-controlled formant filter called the Dipthonizer. The effect’s vocal-sounding vowels and diphthongs provide an animated sonic conversation with hints of phasing, wah, and talk box interplay. Originals are rare, so pedal pushers have produced clones of the endangered effect. One such gadget is TWA’s Little Dipper 2.0 with an analog circuit and some new additions, including a bass boost and expression-pedal support.

Across the Galaxy
Like the first-generation Little Dipper, the 2.0 version has a sparkly, midnight-blue finish. When you connect the 9V adapter (there’s no battery option), a constellation of LEDs lights up. Input and output jacks are on the right-hand side of the box, with the expression-pedal input and power adaptor on the left.
