Under the Sea! Cloning the Quirky EQD Sea Machine

I've been on a bit of a modulation pedal kick lately because I'd gotten some requests from friends, including this build, a clone of the Earthquaker Devices Sea Machine. Touted as a "super chorus" pedal, as with most EQD modulation pedals, this one isn't a one-trick pony and has several very unusual controls that provide a very wide tonal palette. While it is still in production, the "real thing" runs around $199 brand new, so it isn't exactly a cheap pedal - making it a decent candidate for cloning.
