As ever, you will be attempting these modifications at your own risk – if you invert your power and blow something thats on you 😀įrom here let’s add a gain circuit with the op amp. I’m indicating “wires” containing power by red, while “wires” that are at ground are colored black on the diagrams that show the part. Also, these schematics, like many others, “assume” that the viewer knows which two pins are going to connect to the power. It’s just one of those “it’s commonly understood” type of situations amongst circuit builders.

On this schematic and in many simple circuits like this, all grounds are connected together even though they show individual triangles.

A battery has two different connections on it… positive and ground. This symbol indicates ground, which can be thought of as the opposite of positive voltage in this instance. You’ll notice that there is a + or positive symbol, and the other side has a triangle pointing down. This power circuit originates from the battery, marked BAT1 above. R7 controls the gain of this circuit by changing the voltage bias, consisting of a 470k resistor which you can increase or decrease in value to adjust gain before the next stage. When the pedal is on, signal travels to Q6, through C3 and into a transistor gain stage.

In order to make the op amp work properly, we are going to “bias” the op amp using R41, which connects to a simple power circuit.
