The EarthQuaker Devices Sea Machine V3 Super Chorus pedal is a versatile powerhouse that takes the conventional chorus effect and turns it on its head with its extensive modulation capabilities.

The pedal excels in both live and studio settings, offering shimmery choruses, wobbly detunes, and even seasick pitch bends.

Wild. But…

This pedal is like most Earthquaker pedals- capable of doing light modulation or effects, but also just as likely to produce sounds of complete madness. I want to love this, I really do. I believe in the company and their products. Something just isn’t doing it for me though. If, like myself, you want a more standard chorus that can thicken things up and get that nice icy 80s clean sound, this probably isn't it. This, no matter how I mess with the settings, isn’t giving me that. I don’t think it’s trying to though so I can’t fault it. Check out some videos and see what you think. Might be perfect for you if you want something unusual!
