Overdrive

DIY PCB for building a Marshall Bluesbreaker clone - the 1960s amp-in-a-box that spawned boutique overdrive.

Aion FX from Des Moines, IA has helped guitarists build studio-quality effects since 2011. They excel at documenting circuits that became foundations for countless boutique pedals.

The Cerulean recreates the classic Marshall Bluesbreaker overdrive topology designed to mimic the Bluesbreaker amplifier from the 1960s. This circuit serves as the basis for legendary boutique pedals including the Analogman King of Tone and JHS Morning Glory - builders can replicate these variations using different component configurations.

The Bluesbreaker circuit pioneered the concept of amp-like overdrive in a pedal format. Its simple op-amp gain stage with feedback clipping delivers responsive, dynamic breakup that cleans up with your guitar's volume knob. The Aion PCB includes options for exploring multiple boutique variations from a single board.
