The Malekko Goatkeeper (MGK) is a completely redesigned version of the Lightfoot Labs Goatkeeper, first released in 2007. The core of the pedal is an all analog tremolo circuit using a THAT Corp VCA, which when combined with the built in waveforms, can produce tremolo sounds from percussive to smooth. The MGK’s LFO generation consists of two stages, each with a range of multiplier values and waveform selection.
