Pedal sounds very warm and I like that there are only two controls speed and depth, as in my opinion it is enough for a good quality unit. I wanted to buy back the pedal but unfortunately was not for sale. Pedal was in the repair service nearly a year ago and unfortunately I do not have pictures of PCB bottom as well as audio recordings.

Interesting. I would have expected them to be exactly the same:

Google is your friend... :wink: Checking out the various brands with the same PCB bring this one at DIYSB! :D

BTW both "Omnifex" and "Cyclone" aren't in the Discofreq's database as identical to this chorus... :scratch:
