Moog Sub 37
The thunderous heart of the drop, delivering warm analog power to every beat.
The Moog Sub 37 is a semi-analog synthesizer that has become an iconic fixture in Skrillex's live performances and studio productions. Known for its thick, warm bass tones and distinctive filter sweeps, this instrument serves as a primary tool for crafting the heavy low-end that defines his signature dubstep and electro-house sound. While digital workstations handle complex sequencing, the Sub 37 provides the tactile, organic feel essential to his dynamic mixes.

Lore & Background
In the sonic landscape Skrillex has built, the Moog Sub 37 acts as a bridge between raw mechanical energy and digital precision. It is often seen on stage, bathed in strobe lights, where its physical knobs are manipulated in real-time to create evolving textures that shift the mood of a track instantly. The instrument's ability to produce massive sub-bass frequencies without losing clarity makes it indispensable for the genre's most intense moments.
In Their Own Story
The stage lights cut through the haze as the crowd roared, waiting for the silence before the storm. Skrillex leaned over the Moog Sub 37, his fingers twisting the cutoff knob slowly. A low rumble began to build, vibrating through the floorboards and into the chest of every fan in the arena. He didn't just press a button; he sculpted the sound, pushing the filter open until the bass roared like a waking beast, signaling the moment everything would drop.
Reader's Guide
To recreate the signature Skrillex bass using a Sub 37 or similar semi-analog synth, start by selecting a sawtooth wave for both oscillators. Detune them slightly to create a thick, chorusing effect that fills out the stereo field without losing mono compatibility. Next, engage the low-pass filter and set the resonance high. This is crucial for that 'squelchy' sound often heard in his drops. Automate or manually sweep the cutoff frequency from low to high during the build-up to create tension. For mixing, ensure your bass sits firmly in the sub-range (40-60Hz) while letting the mid-range frequencies handle the distortion and character. Sidechain the synth heavily against the kick drum to maintain punchiness, a staple of his production style.
Did You Know?
- The Sub 37 features a unique 'Unison' mode that stacks multiple voices to create incredibly wide and powerful chords.
- Skrillex frequently uses this synthesizer alongside his custom-built modular rigs for live improvisation.
- The instrument's analog signal path is responsible for the warm, non-digital distortion found in many of his classic tracks.
Frequently Asked Questions
What type of instrument is the Moog Sub 37?
It is a semi-analog synthesizer built by Moog Music that Skrillex incorporates into his workflow. The unit includes two oscillators per voice alongside analog voltage-controlled amplifiers and filters.
Why is this synth important to his sound?
He utilizes it to create deep, resonant low-end sounds that characterize his dubstep tracks. While computers manage complex patterns, this hardware offers the hands-on control necessary for energetic arrangements.
What specific sonic qualities does it provide?
The device is famous for producing rich filter movements and substantial bass weight within a mix. It supplies an organic texture that purely digital plugins often struggle to replicate accurately.
Does Skrillex still perform with this equipment?
Yes, the synthesizer remains a staple in his current live shows and recording sessions. He continues to use it for generating both foundational bass lines and melodic lead textures.
How does it fit into his overall production setup?
Digital workstations typically handle sequencing tasks while this analog unit focuses on tone generation. This division of labor ensures his electro-house mixes retain a dynamic, human element.
