Greetings everyone.
I've been looking at the schematics of Greengage overdrive, and the purpose of capacitors C2 and C8 remains unclear to me. (De)coupling capacitors are used for two things: 1) to separate parts of the circuit with different DC bias; 2) to make high pass filters. Thanks to bipolar power supply the entire audio route is biased to the ground and negative feedback cap of the gain stage provides more than enough of high pass fitering. Furthermore, in a very similar Bullrush overdrive there is no cap between input buffer and gain stage.
So, will there be any negative consequences after replacing C2 and C8 caps with jumpers, or they can be safely removed for the sake of reducing the price of the build and deducting the (microscopic) noise of those two caps?
