I'm thinking of building a chorus for my board, looking at options. My favorite I've played through is the Dunlop Rotovibe, and so far my favorite DIY chorus that I've auditioned on YouTube is the Zombie (of which I've also read some horror stories). What chorus pedals have you built, and which was your favorite?
Build Your Own Clone Analog Chorus. The older version, not the current, which is based on the Boss CE-2. The older version was based on the Small Clone. Oddly enough I don't use it for chorus, but for vibrato, with a vibrato mod.
