Analogman Chorus. I had the mini chorus that was good as well, but now I have the stereo version
I have tried a bunch and am a sound purist. All I keep on my board is some strymons, analogman, empress, lehle. I'm sure there's other good brand out there. But to me even tc electronic and Boss color the sound of my signal.. Often there is a slim difference that most will never hear but when these pedals are in my signal chain I can tell the difference.. Also there are 2 types of Chorus in my opinion. There is the more digital ones like on the strymon mobius or eventide h9 or pedals like analogman that are more analog sounding.
Cheers
