Malekko Heavy Industry Goatkeeper

Completely redesigned Lightfoot Labs Goatkeeper, first released in 2007, this is the Malekko Heavy Industry Goatkeeper

The core of the pedal is an all analogue tremolo circuit using a Corp VCA, which when combined with the built in waveforms, can produce tremolo sounds from percussive to smooth.

The MGK’s LFO generation has two stages, each with a range of waveform selections.


  • 2-stage LFO with Sequential, Composite, and Modulation modes
  • LFO modes create sounds from simple to complex rhythms
  • Stage 1 multipliers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, Random
  • Stage 2 multipliers: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
  • Waveforms set singly at each stage
  • Sine, square, pulse, long square, ramp up, ramp down waveforms available
  • Randomize waveforms on Stage 1
  • Rate and Depth controls
  • All analog signal paths using that Corp VCA
  • Large analog headroom
  • LEDs show the waveform intensity of each stage
  • Relay true bypass with LED indicator
  • Detented knobs for quick and accurate settings
  • Tap tempo via Malekko Lil’ Buddy or sync with an external metronome/clock
  • Single-stage mode for classic tremolo


The two stages have four modes:

Sequential: The two stages are run one after the other
Composite: The two stages are run at the same time and the effective waveform is a polyrhythmic sum  of the two.
Modulation: The two stages are run simultaneously and the second waveform modulates the first waveform.
Single: First stage only for classic tremolo.

Set Tempo with the RATE knob or the Tap/Sync input. The Tap/Sync input accepts a Malekko Lil’ Buddy for tap tempo control, or an analog clock/metronome signal. The DEPTH knob allows the effect to vary from subtle to high intensity.

In Use

  1. Goatkeeper is two tremolos, W1 and W2, with selectable waveforms and use options. The Rate applies to both W1 and W2, so they are always locked in time.
Sequential mode
  1. In SEQUENTIAL mode W1 plays before W2, then changes between the two. The RATE defines the overall tempo of the pedal and the multipliers increase the number of times each tremolo cycles at that rate. Playing with a slower RATE yet setting the multipliers high will allow you to instantly create polyrhythms.W1 features RANDOM multiplier setting (R), resulting in constant rhythm variation. Available waveforms are: SINE, SAW, RAMP, SQUARE, PULSE. These waveforms
    all have their own characteristics. SINE creates the classic pulsing tremolo.
    SAW has an aggressive attacking feel. RAMP creates a volume swell.SQUARE is a hard on/off sound. PULSE is a chopping, short sound.
    Changing the waveforms per tremolo will result in interesting sequences.
    W1 has a waveform RANDOM (R) setting which allows variations in the sequence. In SEQUENTIAL mode, W2 can be in either COMPOSITE or MODULATION.
  2. Note on W1 RANDOM (R) waveform: selecting R after SEQUENTIAL mode sets SEQUENTIAL RANDOM, and selecting R after SIMULTANEOUS mode sets SIMULTANEOUS RANDOM.
Simultaneous mode
  1. In SIMULTANEOUS mode, W2 plays at the same time as W1 and modifies W1. When W2 is set to COMPOSITE, its waveform is added to the W1 waveform. When W2 is set to MODULATION, its waveform will modulate the output of W1, acting as a master output modulation.
  2. W1 SINGLE mode: set W2 to >>. This effectively skips W2.
  3. SYNC to external gear using a steady pulse. This can be analogue clock, gates, triggers, click track, etc.
    TAP tempo for live sync. Establish a tempo with two pulses.
