Fairfield Circuitry Modèle B (ODB) is a specialized, always-on version of the critically acclaimed Barbershop overdrive circuit. Stripped of its footswitch to reduce its footprint, this unit is designed for players who view their overdrive as a fundamental part of their core tone rather than a momentary effect. It delivers the same transparent, low-gain grit that Fairfield is known for, providing the sweet, saggy saturation of a vintage tube amp pushed to its functional limit.
Dynamic Saturation and Tonal Transparency
The primary struggle for tone purists is finding an overdrive that enhances rather than replaces their instrument's voice. Modèle B solves this by utilizing discrete JFET stages that behave like vacuum tubes, offering a natural breakup that stays articulate even at higher gain settings. For bassists and guitarists alike, this means your low-end remains tight and your pick attack remains defined. It provides that elusive "more of everything" feel, making it an essential utility for professional recording and live stage monitoring.
Voltage Sag and Ergonomic Efficiency
The standout feature of the Modèle B is the Sag control, which allows you to starve the circuit of voltage. This mimics the response of a dying tube rectifier, introducing a soft-knee compression and a "chewy" feel to the notes that is impossible to achieve with standard clipping diodes. By removing the footswitch, Fairfield has created a "set-and-forget" tool that fits into the tightest gaps on a crowded pedalboard. It eliminates the risk of accidental bypass during a performance, securing your gain structure throughout the entire set.
