The Gravity Well is a one-of-a-kind analog modulation pedal designed to take your sound into deep, psychedelic territory. With a tremolo on one side and a wavefolder on the other, it already covers an impressive range of textures — but when both sides are engaged, a third effect comes alive. This unique combination creates the Refractor, a new style of rhythmic modulation that warps and un-warps your signal in fluid, expressive, and often otherworldly ways.
From synth-like sweeps and cinematic pulses to alien fuzz, ring-mod-like chimes, sci-fi textures, shimmering tremolo washes and completely new sounds you’ve never heard before, Gravity Well is a playground for the creatively adventurous.
