Key Features
The DSM/Humboldt Sub-Atomic is a compact all-analogue bass preamp designed to deliver huge, aggressive bass tones while maintaining clarity, punch, and low-end definition. Featuring dual channels, cascading CMOS gain stages, and parallel signal processing, it produces heavily distorted bass sounds without sacrificing the natural body and fullness that bass players rely on. Whether you're adding gritty edge to modern rock tones or chasing extreme high-gain bass sounds, the Sub-Atomic balances raw aggression with practical tone shaping and responsive analogue feel.
The clean channel delivers warm tube-like response with subtle compression, while the dedicated Sub-Atomic drive channel introduces powerful distortion with an integrated clean blend to preserve low-end weight and articulation. A shared 3-band passive EQ provides tone shaping across both channels, while the onboard analogue 8x10 cabinet simulation and balanced XLR DI output make direct performance and recording setups simple. An integrated FX loop allows easy use of post-drive effects without requiring a separate DI box, and soft-touch footswitches provide smooth bypass and channel switching.

The Sub-Atomic is designed for bass players who want heavy distortion without losing clarity or low-frequency impact. Its cascading CMOS gain stages create aggressive saturation with responsive analogue feel, while parallel processing helps preserve the natural fullness of your bass tone. This keeps distorted tones punchy and defined rather than muddy or unfocused, making the pedal ideal for modern metal, hard rock, and driven alternative bass sounds.
The pedal combines separate clean and drive channels for a broad range of usable bass tones. The clean side adds subtle compression and tube-like warmth, while the Sub-Atomic drive channel introduces far more aggressive distortion with a clean blend control to retain low-end weight. Additional controls such as the voicing switch and selectable low-pass filter settings allow you to shape the attack, saturation, and bass response to suit different rigs and playing styles.
An onboard analogue 8x10 cabinet simulator helps recreate the response of a classic large-format bass cabinet when running direct. Combined with the balanced XLR DI output, it allows easy connection to front of house systems, studio interfaces, or stage setups without requiring an additional DI box. The integrated FX loop also makes it easy to place modulation, delay, or ambience effects after the drive section while maintaining cleaner routing.
The Sub-Atomic keeps operation straightforward with a clear control layout and no menu diving. A shared 3-band EQ centred around carefully chosen bass frequencies provides practical tone shaping without becoming overly complex, while soft-touch footswitches ensure smooth bypass and channel switching during performance. Compact dimensions and standard 9V DC power make it easy to fit into almost any bass pedalboard setup.
