These are the most popular BOSS pedals. Everyone needs them!
Modulation pedals change the pitch of a note over time. Choruses, Flangers, Tremolos, and Phasers are Modulation Pedals.
Tone-shaping pedals are EQs and Filters that can change the overall tone of your sound, like the tone controls on an amp, but with a lot more control.
BOSS's history of pedal innovations includes several time delay pedals. BOSS developed the first digital delay pedal, the first combination digital delay and digital reverb pedal, and the first intelligent pitch shifter in a compact pedal.
Pitch Altering pedals generate notes other than the one you're playing, so you can play chords or harmonies or different octaves from a single note.
BOSS has three dual-purpose pedals that function as both effects and power supplies at the same time.
