A lot of people say the Joyo Ultimate Drive is a clone of the Fulltone OCD. Considering the Joyo is almost $100 cheaper, obviously there's a lot of cost conscious guitarists wondering whether or not is true.... so.... I decided to do a side by side demo, trying to match the sounds of each pedal, to see.
You be the judge.
Personally I find them almost spot on with certain setting, however.... while playing, the OCD has a bit more of an open feel to it, vs the Joyo which has a lot more gain on tap, not to mention a much darker tone control. You'll notice I generally always have the tone on the Joyo turned far more clockwise to match the tone of the OCD. And conversely the gain knob on the OCD is turned up more to match the gain of Joyo.
