Mosky Audio "King Rat".JHS PackRat "inspired" pedal teardown.

This pedal cost me $50aud inc shipping from AliExpress. It features a rotary switch that selects the clipping diodes for the circuit. The only appreciable differences between the flavours of Rat pedals is the clipping diodes. The toggle switches between the two different opamps. Given it's a DPDT, it'll just be switching the outputs of the 2 opamps. The "LM308" is SOCKETED. From the factory. I later checked, and it's definitely a fake 308 I put in a genuine 90s 308, and the sonic difference was quite noticeable. I will be socketing the OP07, too. This will enable me to toggle between a real LM308 and the one in situ. Added afterwards::: I did not socket the OP07 yet. I will make a new video if I ever get around to it.
