Built for unapologetically extreme metal, the Dr. Scientist Dungeon Crawler stands as the brand’s most amp-like and ferocious distortion pedal to date. Designed to transform a clean amplifier into a roaring high-gain monster, it relies on a completely original circuit rooted in three dedicated MOSFET gain stages to handle all internal clipping and saturation.
While forging its own heavy path, the pedal tips its hat to legendary high-gain history: its active EQ is built around gyrator stages that channel the chainsaw bite of the classic Boss HM-2, while a dedicated Grind control introduces a silicon NPN transistor rectifier stage to capture the tattered, aggressive edge of a Boss FZ-2.
- MOSFET Saturation Engine: Three cascading MOSFET stages deliver a massive gain range, moving effortlessly from a subtle breakup to total death metal saturation.
- Iconic EQ & Grind Controls: Gyrator-based equalization offers deep, surgical frequency shaping (from scooped mid-ranges to aggressive boosts), paired with the FZ-2-inspired Grind control for extra upper-register grit.
- Clean Blend & Noise Gate: A built-in noise gate tightly clamps down between heavy riffs, while a clean blend preserves low-end definition and pick attack at extreme gain settings.
- Dual-Footswitch Layout: Features a secondary footswitch that instantly engages a Boost mode, kicking up both volume and gain for screaming leads.
Ruggedly constructed and fiercely articulated, the Dungeon Crawler is a masterclass in modern, heavy-hitting distortion.
