Description

Lil' RAT, your go-to distortion pedal for every gig, whether it’s rock, blues, punk, or jazz. This is the standard sound that all other distortion devices are measured against. Heard on thousands of recordings, it has helped define the sound of the past three decade’s most influential bands. And now 1/2 the size!

The Lil’ RAT features the same controls and tone as the full sized RAT, but only 2 inches wide. It’s built like a tank with rear mounted power and audio jacks. At half the size, this pedal conserves valuable pedalboard real estate, and provides full-sized RAT tones, attack and sustain.

The beauty of the Lil' RAT lies in its versatility. Used as a primary distortion, it excels at arena rock rhythm tones and soaring leads. Do you have a powerful amp with too much headroom for the gig? Let the Lil' RAT be your dirty channel. Maybe you already love your amp’s distortion. Use the Lil' RAT as a boost for solos and get the extra kick you need.

The Lil' RAT features the legendary RAT filter control. Turn it to the right to roll off brittle high-end frequencies. Having trouble cutting through the mix? Turn it to the left and allow the natural brightness of your instrument to shine through.

Distortion dials in the perfect amount of gain – from mild overdrive to full out fuzzy assault, and the volume control lets you dial it in just perfectly against your bypassed clean tone.

Critic Reviews

Pro Co Lil' Rat review | Guitar World

guitarworld.com

The Pro Co Lil' Rat brings the iconic distortion sound of the original Rat 2 into a compact package, perfect for any pedalboard. Its hard-clipping distortion is versatile and retains that classic fuzzy character, making it a steal for under $100. However, the absence of battery compatibility might deter some users. While the controls are smaller, they effectively manage the distortion and filter, allowing for a wide range of tones. In essence, it delivers the nostalgic 'Rat' magic without the bulk, though some may miss the traditional battery option. For those looking for authentic distortion in a mini format, the Lil' Rat is a solid choice.

Pro Co Lil’ Rat review | MusicRadar

musicradar.com

The Pro Co Lil' Rat packs a legendary distortion sound into a compact design, delivering versatile tones that can go from gritty drive to saturated distortion at an incredible value. Its top-mounted jacks are a practical touch for crowded pedalboards. However, the downsized controls can be a challenge in low-light settings, making adjustments tricky. Still, for under $100, this micro marvel is hard to beat for anyone looking to add classic Rat tones without taking up too much space.
