The Supreaux Deux is a distortion stompbox that is adapted from the Supro 16T amplifier. It is known for its unique and characteristic tone, which sets it apart from other famous amplifier brands. The circuit design of the Supreaux Deux includes three gain stages that closely follow the topology of the Revisited Fetzer Valve. It also features an 18V supply for increased gain, headroom, and output capability. The miller capacitance of the first stage is included for a mellower sound, and the output impedance of each valve stage is considered for accurate tone shaping. The pedal also offers the option to add an extra capacitor with a switch to fatten up the sound.

The Supreaux Deux captures much of the amp’s tone, including its brilliant treble response and wide range of sounds. It is particularly well-suited for articulate blues or classic rock sounds. The pedal is highly sensitive and dynamic, so it responds well to changes in guitar volume and pick attack. It is recommended to use a supply voltage of at least 15V to maintain the circuit’s gain and tone.
