Vintage Electro Harmonix, The Clone Theory, in good used condition.
These versions are known for being noisy.. this one isn't. its as quiet as any modern analogue chorus I have used
This is the more sought sought after and rarer late 70s first edition the one with Edge switch and SAD1024 chip, the same version Peter hook uses to get his signature sound , not the early 80s version with the MN3007 chip and the flange switch that sounds more like the Roland ch1 Chorus
