Sound-effect foot pedal for electric/electronic musical instruments

A musical effects apparatus comprising:

• an input port for receiving a musical signal;
• at least two amplitude modulators, each modulator receiving an input from a respective oscillator;
• and
• and integrated foot-operated treadle communicatively coupled to the least two oscillators, the integrated foot-operated treadle allowing simultaneous hands-free adjustment of the at least two amplitude modulators.

A musical effects apparatus comprising:

• an input port for receiving a musical signal;
• at least two modulators, each modulator receiving an input from a respective oscillator;
• and
• an integrated foot-operated treadle communicatively coupled to the at least two oscillators, the treadle allowing hands-free adjustment of at least one of the at least two modulators, wherein one of the modulators pans the musical signal between two channels of the stereophonic output whereby the pan rate frequency is controlled by the integrated foot-operated treadle.

A musical foot-pedal effect comprising:

• a housing with a top side;
• an integrated foot-operated treadle comprising an aperture, the treadle pivotally coupled to the top side of the housing and adapted to vary at least one musical effect;
• an input port for receiving a musical signal;
• a modulator coupled to the input port and adapted to modulate the received musical signal;
• and
• a visible user interface adapted to display a modulation frequency of the modulated signal, the visible user interface disposed on the top side of the housing and disposed at least partially within the aperture of the treadle.
