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...

Checking out the various brands with the same PCB bring
this one at DIYSB!
BTW both "Omnifex" and "Cyclone" aren't in the Discofreq's database as identical to this chorus...
