Crazy Tube Circuits / Motherload

The Motherload is a fuzz distortion pedal that consists of two completely analog circuits that can switch between the legacy sounds of the classic Proco Rat and EH Big Muff pedals using a toggle switch.

R mode
This mode allows you to create a wide range of sounds, from overdrive sounds that express subtle touch nuances to roaring distortion. You can create both piercing, intense distortion sounds and fat, warm sounds by adjusting the Filter knob, which suppresses the high-frequency range.

M-mode
M-mode, which is characterized by a biting distortion sound that is part of the history of fuzz, is perfect for creative guitar riffs with a strong sense of attack that changes depending on the picking and touch. The Tone control can be used to suppress the high-frequency range and emphasize the low-frequency range. The Voice control accurately captures the variations of the BIG MUFF, and you can feel the history of the various models.

LINK EQ switch
When the LINK EQ switch is turned on, the three tone controls are enabled in both R/M modes. This allows you to create a wide range of sounds that are not possible with the original.

This unit operates on 9V DC.
Please be careful not to apply a voltage of 15V or more, as this may damage the unit.
