Gyroscope is a Filter modulated by six different waveforms.

What the knobs on this do? the Vol controls the input gain that is filtered, unity gain is achieved aprox. at 50% of the dial. The Resonance amplifies a narrow band near the filter cutoff increasing the filter volumen, affecting the open-ness of the vowel . Range  selects how much the wave is going to modulate the filter, changing the cutoff freq, you can get some pseudo phaser-like tones. Aux a fine tune for the range knob, when the range is at it lowest position, increasing the Aux will turn the gyroscope into a fixed filter, to give you the option to use it as tone shaper to get those fixed wah type of tones. Ratio will change the rate of your original tempo in 1x, 2x, 4x or 1/2x of your original Tap. Wave selects from square, sine, sample and hold, triangle, escallonated or ramp up. Gyroscope is only powered via a 9v DC adapter (center negative as most pedals - boss, digitech, etc) there are no options for battery usage.
