The Crazy Tube Circuits Motherload is an all-analog distortion and fuzz pedal that combines two classic gain circuits—a Big Muff-style fuzz and a RAT-style distortion—into one compact box. It features a toggle switch to select between the Muff (fuzz) and Rat (distortion) circuits, each with its own EQ controls, and a Link EQ button that activates all tone controls together for unique combined tonal shaping. Controls include Volume, Gain, Tone (Muff), Voice (mid character for Muff), and Filter (high-cut for Rat), giving a wide sonic palette from saturated fuzz to roaring distortion. The pedal runs on standard 9 V DC with true bypass.
