Grendel Drone Commander Classic Pedal

This pedal revives the raw analog heart of the original Drone Commander from 2008, packing those legendary thick drone tones into a stompbox-sized powerhouse that's perfect for pedalboards.

Dual analog oscillators churn out triangle or square waves from 20 Hz to 360 Hz, blended via a mixer that also welcomes external audio through a 3.5mm mono input for processing guitars or other signals with adapters. A gritty bandpass filter follows, with switchable cutoff ranges, resonance that self-oscillates at low settings, and overdrive controlled by a trim pot—plus CV input for external modulation from -10V to +10V. The LFO swings a ramp waveform (rising or falling) mixed with PLL-generated clicks at 2x-16x multiples, delivering rhythmic sweeps over a wide speed range, all tweakable with knobs for depth and intensity. A footswitch or gate input triggers an AR envelope for fast or slow fades, while clock out enables tremolo loops, and a VCA handles volume—all in a rugged 6.3 x 4.1 x 2.1" enclosure powered by 9V battery or pedal supply.

Players love its hands-free performance integration and versatile filter effects, though some note the 3.5mm jacks require adapters for standard rigs—making it a drone specialist rather than a straight guitar pedal.
