EarthQuaker Devices · pedal
The EarthQuaker Devices Sea Machine is a deep, highly tweakable analog voiced chorus offering a vast range of modulation, from subtle, shimmery classic chorus to wobbly, seasick, warbly pitch bent detuning. With controls for rate, depth, shape, dimension and a wide ranging clock that affects the chorus character, it goes far beyond a standard chorus into lush, watery and downright disorienting textures. It suits players from clean rhythm and ambient to experimental and shoegaze who want everything from gentle, dimensional thickening to extreme, drunken pitch warble. Its depth of control makes it one of the most flexible and characterful chorus pedals available, equally at home subtle or wild.
