Re: 805 vs ocd
An OCD is a distortion pedal, it has more gain than thje 805, which is an overdrive. Distortion pedals can be used as an overdrive if you set the gain low, and an overdrive as a distortion if you max out the gain. The main difference is that they are designed to sound best doing one thing or the other.
You can go either way, if you get the 805, you can stack the 805 and the Klone, you get two flavors of overdrive, or you can stack them and get a roaring lead tone. Or you can get the OCD, have a dedicated OD, a dedicated distortion, and stack them for a lead tone that feeds back like crazy (in a good way) and gives up the squeelies. I have three overdrives, two distortions and three fuzzes on my board, so I can't settle on any one thing.
Also note that neither the OCD or 805 is an "amp in a pedal", so how they sound varies heavily from one amp to the next.
The Joyo Ultimate Drive and the new Caline CP-21 are OCD clones. You can score one of those for about $40.
