Looking for a dynamic, responsive pedal that gives you cranked-tube amp crunch — even at low amplitudes? The Catalinbread Formula 5F6 can serve capably as your go-to source for Bassman tone stack circuitry in a pedalboard-friendly format. Whether you’re playing into a high-powered Twin or a boutique head and cab, the Formula 5F6 can form the foundation of your pedalboard chain.

This JFET-driven little monster has Treble, Middle, and Bass tone controls for shaping the mix to suit your music. You also get Volume and Gain knobs for finding the sweet spot — the level that lets you expressively reach from sparkly clean sweeps to raunchy blues double-stops and throaty bends with the flick of your wrist — even at neighbor-pleasing volumes.
