Mooer Slow Engine Slow Motion Effects Pedal

Violin-Like Volume Swells

The Mooer Slow Engine recreates the classic volume swell technique, mimicking the effect of rolling your guitar’s volume knob to eliminate the attack of a note. The result? Smooth, expressive tones that rise gently—sounding almost like a bowed instrument or ambient pad. This slow fade-in makes it perfect for post-rock, cinematic, ambient, or experimental styles where soft transitions and lush soundscapes are key. It’s like having a hands-free volume swell in a tiny box. With its simple interface, it helps transform clean tones or adds unique character when paired with reverb and delay. Whether recording or performing live, it brings instant emotional texture.

Compact. Rugged. Space-Saving.

Built with a full metal shell, the Mooer Slow Engine is not only compact but incredibly durable—ready for any stage or studio setup. Its mini size (93.5mm × 42mm × 52mm) makes it ideal for crowded pedalboards, yet it doesn’t compromise on sound or build. True bypass ensures that your tone remains untouched when the pedal is off. With a weight of just 170g, it’s easy to transport, and its solid construction withstands consistent use. Ideal for musicians who prioritize space and portability, this pedal proves that great effects can come in small packages without sacrificing quality or function.

Simple Yet Powerful Controls

Despite its simplicity, the Slow Engine offers deep musical utility. It features a single effect that’s triggered automatically as you play—fading in your notes for a gentle, slow-attack response. It runs on a 9V DC center-negative power supply and has a current draw of 128mA. Input impedance is 470k Ohms, output impedance is 100 Ohms, ensuring clean and consistent signal processing. With no complicated settings, it’s easy for any player to integrate into their signal chain. Whether you’re looking to add subtle dynamic shifts or sweeping, cinematic swells, the Mooer Slow Engine gives you expressive control in a beautifully minimal form.
