The Analogman Bad Bob Booster is a Class A JFET-based booster designed to provide a significant volume lift while adding a thick, rich harmonic character to the signal. The circuit is based on the "Mini-Booster" JFET mu-amp design originally created by Jack Orman, with whom Analogman maintains an official licensing agreement to use the boards. It utilizes hand-selected, discontinued Fairchild 2N5457 transistors or high-quality modern SMT equivalents to achieve low-noise performance. The pedal typically features a single level control, though some versions include an optional drive knob to adjust the amount of grit. It is widely utilized as an "always-on" sweetener or to drive the front end of a tube amplifier into natural saturation.
