This one, friends, is super cool. Pearl might not be the first brand you think of when it comes to pedals, but they made some cult classics in the early 80s. This one was made at the KLM factory, which also made Ibanez and Maxon pedals back in the 80s. It's got two switches for two modes: the left is pretty traditional chorus, with a level and speed control, but the right gets pretty out there. You get a chorus and a vibrato, with a separate rate and depth control, as well as a delay control to push the two waveforms further apart to really get the ship swaying. It's driven by two bucket brigade chips under the hood and runs on 18v power, so you know it's here to kick ass.
