Earthquaker Devices Sea Machine Mega Chorus v3

The Sea Machine is a chorus pedal with as many modulation possibilities as there are fish in the ocean. That’s a lot of fish. And a lot of modulation. From subtle, shimmery chorus sounds, to wobbly, seasick, warbly pitch-bent detuning that rocks the boat, the Sea Machine is the audio bait that’ll help you reel in the big one.

The Sea Machine ain’t no one-trick seahorse. A variable waveshape LFO (adjustable via the Shape control) modulates your chorus tone from a smooth triangle shape, to a rough and choppy square wave, and an extended delay line allows you to dive deeper into uncharted modulated waters than ever before. Other LFO controls include Rate, which sets the speed of the LFO, and Depth, which sets how strongly the LFO modulates the delay time.

The delay line has controls for Dimension, Animate, and Depth. The Dimension control adds a slightly detuned slapback at low levels, reverb-like ambience at mid-levels, and a trippy echo-resonance that leads to self-oscillation when cranked. The Animate control is the real pearl in the Sea Machine’s oyster, if you will. This controls how far the pitch swings. At lower settings, you’ll hear slight detuning for a subtle double-tracked thickening effect, á la traditional chorus pedals. As you increase the Animate control, the pitch swings further and further away from the root note for an effect that lies somewhere between chorus and vibrato, before landing at full tilt on sonar-like oscillations that sound more like a giant monster-movie beast awaking from its undersea slumber than any effects pedal we’ve ever heard. Finally, the Intensity control rounds out the delay line, adjusting the blend between the modulated and dry signals.

With this mix of standard and unique controls, everything from subtle warble, classic Leslie, seasick pitch bends, strangled alien sounds, stunted arpeggiations and many more far out sounds are available. Or you could just use it as a chorus. That works, too. Oh, and if you’re a bass player who fancies themselves a fan of the classic 80s post-punk bass sound, the Sea Machine is pretty much just like (tone) heaven.

We’ve designed the Sea Machine to work well following fuzz / overdrive / distortion pedals without getting muddy, lowering in output, or breaking up, because we like running distortion pedals into things. Also, when engaged, the Sea Machine’s transparent buffer leaves the all-analog dry signal unaltered and crystal clear.

The Sea Machine is true-bypass, uses silent relay-based switching, and is built one at a time in the belly of the great white whale along the shores of the Ohio & Erie Canal in Akron, Ohio, USA.

• Improved circuitry for better performance, cleaner sound, and lower noise
• More range added to almost every control from subtle modulation to extreme oscillation
• Silent relay-based switching
