Electro-Harmonix Bad
Electro-Harmonix · pedal
The Electro-Harmonix Bad Stone is a classic analog phase shifter first introduced in 1975, notable as one of the first phasers to incorporate a feedback control into its circuit for a more resonant, intense sweep. It offers a six stage phase shift with rate control and a manual mode that lets you set and hold the phase position by hand rather than using the LFO. Its voice ranges from subtle, watery movement to deep, swirling, resonant phasing with a vintage, organic character. It suits classic rock, funk, psychedelic and experimental players who want a warm, characterful vintage phaser with the unusual flexibility of manual phase control and feedback enhanced resonance.
