Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.

From the vendor

Project overview

Based on the Zvex Woolly mammoth, this mighty beast will preserve your sub-frequencies and bring the lowest lows like no fuzz you ever heard before. Are you ready to tame it?

Introduction

Here comes the Hairy Elephant! The low frequencies produced by its uncontrolled stampede can terrify the bravest of the hearts. Lucky for you, this board has a half-gated feel that will give you a roaring fuzz with clear precision in between notes and phrases and an EQ control that smoothly selects between more bass and more treble. This will provide you with absolute control, and once you hold the reins firmly, riding on the back of this behemoth will be a straightforward experience.

The original Zvex Woolly mammoth was initially built as a bass pedal, but you see it on plenty of guitar pedalboards as well. When you look at the schematic, there is no high pass filter that cuts what a bass player needs, and its rough sound benefits from it no matter the scale your favorite instrument has. Also, conveniently, the pinch knob affects the overtone behavior. The sounds of the four knobs easy-to-source project with silicon transistors go from something with the flavor of a broken noise gate to blowing up the amp.
