INTRODUCTION

The Crescent Amp Distortion is an adaptation of the MI Audio Crunch Box, a tweaked hybrid of the

Marshall Guv'nor and Bluesbreaker first released in 2006.

It's solidly in the family of Marshall-like pedals and is lauded for its high-gain "stack of amps" tone. It

has seen has seen at least five major versions since that time, with the fourth and fifth version being

renamed to the Super Crunch Box.

The Crescent is not a direct clone or copy of any of these versions, but rather a hybrid of several of them.

It's most similar to version 3, but with an added option for 18V operation using a charge pump as well

as a clipping diode toggle switch (both features from V5, although our version had it long before V5 was

released!).

The updated version of the Crescent is mostly the same as the earlier 1590B version, with two major

changes. First, there is an internal slide switch allowing 9V or 18V operation to be selected. Second, the

Presence control has been relocated back inside the enclosure as a trimmer, as on the original Crunch

Box units. The presence control essentially just sets the range of the main tone control, so it doesn't

need to be external.

The Crunch Box was the inspiration for another well-known high gain pedal, the Suhr Riot. An Aion FX

adaptation of the Riot is available called the

USAGE

The Crescent has the following controls:

• Tone controls the treble response of the effect.

• Drive controls the amount of gain in the op-amp feedback diode clipping stage.

• Volume controls the overall output.

• Clipping (toggle switch) selects between 3 sets of diodes: 1x silicon, 2x silicon, or LEDs (stock). This

will directly affect the volume, which will need to be adjusted when changing this mode.

• An internal Presence control allows you to tweak the overall response of the tone knob.

• Voltage (internal slide switch) selects 9V or 18V operation.
