By effect type

Modulation Pedals

Modulation continuously varies some property of the sound — pitch, phase or amplitude — and it is what produces the sway of a chorus, the sweep of a flanger, the pulse of a tremolo. It is the effect that takes a guitar out of stasis without changing what is being played. VTR modulation pedals gather those algorithms in a single unit, with an OLED display and MIDI presets.
