Sea Machine™ Super Chorus

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

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.

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
List Price: $199.00 Controls

Rate: Sets the speed of the LFO. The miniature LED will show the tempo even in bypass mode.

Shape: From soft triangle through hard square wave.

Dimension: Adds a slight slap-back at low levels, reverb-like ambiance at mid levels and an echo-resonance at max.

Depth: How much the LFO modulates the delay time.

Animate: How
far the pitch shifted signal swings, lower levels equals a tighter and
more focused shift à la traditional chorus. As you increase the control a
more wild and animated pitch shift begins to emerge.

Intensity: How much modulated signal is blended in with the dry signal.

pedals take a standard 9 volt DC power supply with a 2.1mm negative
center barrel. We always recommend pedal-specific, transformer-isolated
wall-wart power supplies or multiple isolated-output supplies. Pedals
will make extra noise if there is ripple or unclean power.
Switching-type power supplies, daisy chains and non-pedal specific power
supplies do not filter dirty power as well and let through unwanted
noise. Do not run at higher voltages!

Current draw is 50 mA.
