Released in October 2026, the Big Business by Morristown, New Jersey boutique builder Turbulent Audio
is a versatile three-band EQ and dual-footswitch boost created to solve the limitations of traditional tone-shaping tools. Dissatisfied with interactive amp controls, fixed graphic bands, and complex parametric sweep points, Turbulent Audio engineered it with user-adjustable crossover points, broad frequency responses, and completely independent bands.
Running on an internal 18V rail for massive headroom, the circuit pairs a broadband gain circuit with a dedicated, independently switched clean boost that slams the front end of tube amps or downstream drives without introducing unwanted pedal-level distortion.
As highlighted in the demo belowby collector // emitter, this high-headroom architecture makes it a powerhouse for ambient and shoegaze setups. Whether used as an always-on preamp to recover long-chain signal loss, a targeted mid-boost for solos, or a tail-end sculpting anchor that prevents heavy reverberant washes from collapsing into mud, Big Business delivers predictable, mix-cutting clarity across your entire pedalboard.
