The halls of Winter NAMM are usually filled with a pretty eclectic mix of strange gear. Rainger FX, with their Minibar Liquid Analyser Overdrive, sticks out. The Liquid Analyser is no ordinary overdrive. The gain and tone of the pedal can be effected by filling the small container on the front with liquid. The darker the liquid, the darker the tone. Salt & carbonation increase the gain. Talk about a pedal with room for experimentation.
