A floor effect unit for actuating a musical effect device is provided. The floor effect unit includes a base plate having at least one electrode configured to collect electric charges; a conductive plate having at least one pressable portion configured to collect electric charges having a polarity opposite to the polarity of charges collected on the electrode, pressable portion being configured such that pressing thereon reduces the distance between the at least one pressable portion and the at least one electrode changing thereby the capacitance therebetween; and a spacer disposed between the base plate and the conductive plate and being configured to provide dielectric gap therebeteen, a printed circuit board coupled to the at least one electrode and the conductive plate and being configured to generate an output signal for operating the musical effect device in response to a change in the capacitance. |
