2 Introduction & Usage

INTRODUCTION

The Cerulean Amp Overdrive is an updated version of the Marshall Bluesbreaker pedal, originally

released in 1991. In 1995, Marshall moved production from England to Korea, and around this time they

made some tweaks to the circuit, increasing the gain and reducing the bass. It was discontinued in 1999

to make way for the Bluesbreaker II, a redesign that is universally seen as inferior to the originals.

The Bluesbreaker is the source circuit for a number of expensive boutique pedals including the

Analogman King of Tone, which is two Bluesbreakers in the same box with a few modifications. The

Cerulean project borrows the expanded clipping options from the King of Tone, allowing you to select

either soft clipping (stock), hard clipping, or no clipping (boost mode).

We have also added an internal DIP switch to select between three different gain range settings.

Normally to increase the gain range of an overdrive, you'd just raise the value of the drive pot. However,

the Bluesbreaker has a unique dual-stage gain control setup such that increasing the potentiometer

value will also lower the minimum gain along with raising the maximum gain, so this method is not very

useful. But by adding resistance to just the first stage, we can shift the overall gain range higher and get

a lot more tones than the original pedal was capable of.

The third addition is a toggle switch to go between the pre-95 (V1) and post-95 (V2) versions. It's not a

drastic difference, but there's enough lore surrounding the two versions that we thought it'd be worth

including this as a setting.

The Cerulean V2 is a complete overhaul of the original Cerulean, which combined features from the

JHS Morning Glory as well as the Presence trimmer from the King of Tone. The first version is no longer

available, but the

legacy 1590B version

USAGE

The Bluesbreaker has the same control layout as most overdrive or distortion effects:

• 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) lets you choose between soft clipping (stock), hard clipping, or no clipping.

• Mode (toggle switch) changes between the V1 and V2 Bluesbreaker circuits.

CERULEAN AMP OVERDRIVE

of the project is largely the same and will remain stocked. The

Theseus

and the Prince of Tone is available as the Achilles.
