First in "The British Invasion Series" is the Fuzz Pump - Booster. Made from combining ideas behind two of the most sought after British boosters. First it will give you a pleasant tube driven overdrive sound to a clean amp or send your already driven amplifier into tonal bliss. It is also designed to be used in front of any fuzz, overdrive or distortion pedals! The Fuzz Pump is absolutely amazing at driving just about any configuration you have. And by itself will clean up nicely with a twist of your guitar's volume knob! This pedal is also available in a plain gloss color.
