Mosky Black Rat Pedal Review: The Cheapest RAT I Can Find – Guitars For Idiots

guitarsforidiots.com

The Mosky Black Rat pedal, while attractively priced at $31.99, fails to live up to the iconic RAT sound. Despite offering a "turbo" and "vintage" mode, the Black Rat struggles with muddiness and lacks the mid-scoop and high-end clarity of its inspirations, such as the ProCo RAT2. It delivers a bass-heavy, thick distortion, but doesn't cut through the mix or achieve the famous RAT fuzziness. Though it might serve as a budget-friendly option for bass-heavy, rhythm-focused distortion, it falls short as a genuine RAT alternative. Consider saving for a Boss DS-1 or RAT2 instead.

Cheap, solid, and reliable. Won't blow you away but a good product.

Personally I go for heavier distortion styles anyway, but I couldn't afford the fuzzbox I wanted so I decided to run this into my ODB-3 to get more of a fake-fuzz crunch. Biggest complaint really is that the knobs move so easily that its easily to lose your settings just by packing up. Definitely worth your money if you're looking to add to your board on a tight budget.
