...holy smokes this thing is cool! I have only used it as a pre-OD boost so far (my intended purpose for this purchase). It's like 'special sauce' for the CJOD, the Eternity, and the OCD! I have the bias set to about 10 o'clock - just enough of whatever it does. It's hard for me to describe this early on but I like it. I like it a whole lot! I was pretty well ready to sell the OCD but I'm digging it with a little push from the COT. I have a DNA Analogic Gain Fxxker II on the way (the next contestant in my search for a high gain pedal - hopefully the last). For now the OCD is sitting in it's slot on my board. If I don't dig the Gain Fxxker then the OCD will get to stay a while longer. Either way I'm pretty sure I'll be hanging on to the COT!
